Sometimes I can send email, sometimes I can't...

So, I've got the latest version of OSX and Mac Mail. I've checked with my ISP and the port used is not blocked.
Sometimes, I can send email just fine. No problems.
Other times, when I send email I get this error: Cannot send using the server <insert my outgoing mail server here>
Oddly, if I close mail and then restart it - it will often send the emails.
I've checked with my hosting company and the email servers are fine and running. If I do the "connection doctor" from inside mac mail, I get all green - connecting fine.
Any ideas?

If you refer to my posts of a today and a few days ago I've had the identical issue - I do not agree with the posting of the person that followed yours - It is something wrong somewhere - My ISP is Comcast and while they've been very helpful in working with me to solve it the problem persists - it seems to have gotten worse in recent weeks and maybe for the past month or so -
It seems to be in the incoming port - I often have an "offline" reading when I check the preferences - then for no reason it will come back on line and everything will be ok for a while - I have gone directly to the web mail of Comcast and it works perfectly - the port #'s assigned by Comcast are often not working properly and when I change to other ports it will work for a short time - all very mysterious -

Can no longer send email from my accounts but can receive

I have 5 email accounts set up on my imac. 3 are mine 2 are my partners. I can no longer send emails from my accounts but my partner still can. They all still receive mail but when I attempt to send mail I get:-
Cannot Send Message Using Server
Then i'm asked to select a different server from a list. I have tried all but to no avail.
I first of all deleted my partners sky.com account because it appeared to me that this was maybe overiding all other accounts and it was no longer needed on imac.
I then deleted one of my accounts - hotmail, to see if i added it again maybe it would work but now I cant even re add the mail account as everytime i go to mail, preferences account to set it up again the initial screen comes up with my partners details including the sky.com username and when i overwrite these and try to install hotmail acount I get told that logging in failed check user name and password is correct. Which they are.
All used to work fine but now I have these problems, they appeared to have started when my partner set up an icloud account and is synching with this - could this be the cause?
I can send email from my accounts from iphone still but no longer from imac.

First,
I'd run all availiable software updates. After that, I would try removing all of the accounts from "Mail", and then re-adding them. Be aware that if your folders and such are located on your mac, and not on the mail servers, you may risk lose some information (always have a back-up).
Sometimes, when you have a number of e-mail account there can be server issues abound. I would go into the server lists and make sure that they are set properly. If you see the "use only this server" box, check it for each of them.

TS3276 I cannot connect to my outgoing email server on my macBook pro, yet I can, for the same email account on my iPad. Also I can send emails from the other email account I have on my MacBook...really confused can anyone help?

I cannot connect to my outgoing email server on my macBook pro, yet I can, for the same email account on my iPad. Also I can send emails from the other email account I have on my MacBook...really confused can anyone help?

Sometimes deleting the account and then re-creating it can solve this issue
Write down all the information in accounts before doing this
Highlight the account on the left and click the minus button
Then click the plus button to add the new account and follow the prompts

I have an iMac, and have a Verizon DSL account. Recently, my Mac Mail keeps requesting the passwords on my account every few minutes, and will not allow me to send messages using Mac Mail. I cannot edit the outgoing server; how can I send emails?

I have an iMac, and have a Verizon DSL account (3 email addresses). Recently, my Mac Mail keeps requesting the passwords on my accounts every few minutes, and will not allow me to send messages using Mac Mail (the message says that the outgoing server was rejected. I cannot edit the outgoing server, and the keychain will not save my passwords (the ports are valid). How can I change the outgoing server to send emails, and how can I avoid having Mail request my passwords every 2 minutes? Verizon, as usual, will not provide support to iMacs.

Is there an email saved in your drafts or outbox folder? I suspect that Mail is continually trying to send it, and each time Google is rejecting the email message.
You can open the message and then delete it from your Outbox folder. Then try removing all @gmail email addresses from it and seeing whether you can send to the other folks. I suspect that will work.
With email, if an SMTP server *can* verify email addresses, sometimes it will and it will refuse to send messages. If a message has to be relayed across servers, no verification is done, and you'll get a bounce if an email address is bad.

Why can't I send Emails from iPad apps?

When I am using iBooks, or Evernote, or Hootsuite, or just about any application on my iPad that allows me to Email items from within the application, the following happens when I try to send an Email:
1) I click the share button.
2) Choose Emaill
3) Write the Email.
4) Click Send
5) Hear swoosh sound and it appears the Email is sent.
However, the Email is never actually sent. I've tested this mutiple times to various Email addresses and it just isn't sending the Email. The only exception is when I send Emails from within the Gmail app, in which case they send fine.
After discovering this I took our my iPhone 5 and tried to do the same from there with the same applications. I was able to send Emails from within the iPhone applications just fine so this problem is specific to my iPad.
I checked my mail settings and didn't see anything out of order. As I said, I can successfully send Email from the iPad using the Gmail app or just sending it from within a Chrome window.
Thoughts?

I used to be able to send e-mail from within apps on my iPad. Then all of a sudden, I was unable to do it. I changed none of my settings, and my regular e-mail works just fine. One day I could e-mail from within apps, and then next I could not.
When I hit the share button within an app, I then select the e-mail button. An e-mail message opens for composition. It has the subject line filled in, but that's all. It will not allow me to enter the address and it contains no message or link. It's just dead. Sometimes I wait for a while to see if anything changes, but it doesn't.
Did apple change something without telling us?

Can't send emails. Can you help pls? Thanks.

Hi, my Mac Book Pro won't let me send emails. It says: Outgoing mail server (SMTP): Gmail Offline. Can you help pls? Thanks.

Help. I have the same problem. I can receive email but can not send email from my MacBook Pro running OS X 10.9.4.
I have been reading posts about this issue until my eyes are rectangular.
I have tried the following:
1. Removing the passwords from the keychain.
2. Trying the various ports (default set, custom 25 alone, custom 465 alone, custom 587 alone)
3. Unticking the Use SSL box. Interesting note, it sometimes self-ticks this box.
4. Supplying full email name in the userid box. Interesting note, it sometimes self-corrects to just the plain userid prefix.
5. Running repair disk permissions
6. Turning offline all mailbox accounts and then turning then back online.
7. Rebooting numerous times
8. Force Quit of Mail and numerous normal quits and restarts.
9. All software updates have been installed.
10. I may have forgotten some of the more bizarre things I have tried but I have not got to the point of deleting the entire account (and all of its 3 years of emails).
I have a sister MacBook Pro (same operating system, larger screen, same ISP, same email provider, same power source, etc.) sitting right next to this one and it is working fine - mail comes in and mail goes out. It is on the same network and I have dutifully copied all of the parameters and this still does not solve the issue. Surely, there is more witchcraft out there that I can try? New to this "posting" process. Not even sure how to get back to see if anyone has any further suggestions. Thanks to all those who have tried to provide suggestions. Much appreciated but I am still stuck with webmail! Arghhhh. Ron

Can I send email invitations to local users instead of push notifications?

I see in the documentation that "Attendees can be invited to events via email if they don’t have an iCal Server account." Is there a way to send email invitations to local users instead of push notifications? The server would be migrating from Exchange and everyone is accustomed to/wants email invitations for calendar events.
I've already purchased a copy of Lion Server (10.7.4) and pretty much everything is setup. Sadly I'm just now running into this issue. Email invitations to non iCal server accounts work fine.
Thanks for the help.

Hi gracem0324,
Go to Settings>Messages>Send & Receive, and click on your Apple ID and sign out of Messages. Then sign on again. Sometimes it needs to reset itself....

Having a problem sending email, I have tried all the fixes, but no luck, actually it works at times and most times it does not. What more can I try.

Issues send email from my macbook Pro, it is a web based email, and I can send it by logging into the webmail site. The odd part is that sometimes it just works and most times it does not. I go through and make some random changes and and then go back and change it back and it wold work for that email, and then a few minutes later I try to send another and does not work, try doing the same and this time it does not work, getting a little frustrated, what else can I do, except chage back to a windows based laptop?

If you're having trouble sending, but not receiving, mail, it's likely due to your outgoing (SMPT) server settings.
Which webmail service are you using? Some provide some good guidelines on setting up your account, some not so good.

Can't send email through SMTP server

As some others have reported, I recently started having problems sending emails (most of the time) through my regular smtp server (receiving is not an issue). Once in a while it does go out, but most of the time I get a message "Can't send message using the server smtp.XXXX.com". I know it's not the smtp server as I can go out with my browser and use webmail and it sends fine, using the same server.
It only affects this one main email account - my other accounts seem fine (including gmail, mac, and another pop accounts), at least so far.
It is extremely frustrating - saw a whole lot of ideas for fixing it (changing ports, etc.), but don't want to mess up all the accounts that are working. I'm a long time Mac user, but not a real techie.

I know it's not the smtp server as I can go out with my browser
and use webmail and it sends fine, using the same server.
This is wrong. Whether you can send via webmail has nothing to do with whether you can send using a standard mail client such as Mail. The outgoing server that ends up delivering the message may be the same in both cases, but the outgoing server you communicate with is not. Actually, when sending via webmail you don’t even use SMTP to communicate with the outgoing server.
There are circumstances under which you may not be able to send using a standard mail client such as Mail no matter what you do (e.g. because the ports needed for SMTP are blocked by the ISP at the location you’re trying to send from), whereas webmail works fine — and may be your only option in those cases.
If it works sometimes, that means your account settings are probably correct, but you cannot discard that there is a problem with the outgoing (SMTP) server that Mail has to communicate with, even if sending via webmail works fine.
<hr>
That said, go to Apple Menu > System Preferences > Network, choose Network Port Configurations from the Show popup menu, and make sure that the configuration used to connect to Internet appears at the top of the list. Leave checked (enabled) only the port configuration needed to connect to Internet and Built-in Ethernet (in that order if not the same), uncheck (disable) the rest of network port configurations and see whether that helps — if it doesn’t, turn ON again the ones you want enabled.
Try using a different method to connect to Internet, if possible, or connecting the computer to Internet as directly as possible (i.e. bypassing any routers that might be present, using an ethernet cable instead of wireless, etc.), or shutting down both the computer and the router/modem used to connect to Internet, restarting, and see whether that makes a difference.
Mail keeps information about outgoing (SMTP) servers in a separate list independently of the mail accounts themselves. The account settings just associate one of the available outgoing servers with each account. Orphaned or dangling outgoing server entries (i.e. not associated with any account) sometimes cause weird sending problems.
Go to Mail > Preferences > Accounts > Account Information > Outgoing Mail Server (SMTP), choose Edit Server List from the popup menu, and delete any servers that shouldn’t be there — the Edit Server List panel shows the account each outgoing server is associated with.
If the problem persists and you have more than one mail account, try moving the account that has the problem to the top of the list in Preferences > Accounts.

TS3899 can't send email on iPhone 5

Hi,
Yesterday I changed my email password on my PC. After which I went to settings on my iPhone 5 and changed there the password (for the new one).
I can receive but not send emails... What's the problem?
Thanks
Ola

Comcast can be interesting sometimes. They have been my provider, and have had some issues, especially when they changed the port number they use for mobile devices. They have a support page specifically for the iPhone settings, but you may want to delete the account from the iPhone and re-enter it, making sure to enter the username and password everywhere it asks for it, even where it says optional. See this picture for SMTP settings for Comcast.

Hosted Email Server can not send emails to certain domains including Hotmai

I host my own email server and domain, but when I try to send emails to certain domains Hotmail being one of them, It gets refused saying something about spamming, when I know I am not a spammer because only one of the users in my domain can actually send and receive emails.
Is there a list I can include my domain in, so that I can bypass the spammer status?
Any help is greatly appreciated it.
Thanks!

This is getting common as people attempt to cut down the spam.
Check your reverse dns is correct, I'd suggest an external test like http://www.mxtoolbox.com/ against your system/domain is a good place to start.
In the case of the problems I had at home a while back this was down to my ISP not setting up the reverse DNS correctly. I got the Reverse DNS not matching the SMTP Banner i.e. IP address then ISP name:-
xxx.xxx.xxx.xxx.btopenworld.com
Microsoft and some other companies introduced a while back the use of SPF records, so check your zone file info to make sure this is there and valid.
http://old.openspf.org/index.html will help here, if you haven't got SPF set-up.
Some ISP's employ Goodmail systems, now which isn't a problem for small companies/home users sending small amounts of email, but will effect large companies.
If you're not sending large amounts of email to AOL, Hotmail, Yahoo etc this shouldn't effect you. Basically, it will force a 'drip feed' into their email systems. One company I worked at had to send email to customers, and this meant the first few emails would be accepted, then the server wouldn't accept more email for 20 minutes or so, then it would take another 5 emails, and so on....
Dynamic IP addresses, from your ISP can also cause huge problems. If you haven't got a fixed IP address, many systems will reject email. Even if you have a static IP address, ensure your ISP has this correctly allocated. Sometimes, you'll get it from the wrong range (ones which normally are Dynamic), and this will cause problems. 'Cheap state' ISP's can often allocate you a fixed IP, but because they have 'run out' of fixed addresses, they may pinch a dynamic one....
Some places check your MX records http://vger.kernel.org/mxverify.html will help here. It's a bit of a cheat, as large companies may not have the same outbound servers as inbound servers, but I have seen this cause problems when ALL the mail servers are not listed in the MX records.
The only one I wouldn't worry about too much is the Goodmail system, unless you're sending large amounts of email. But even then, they normally only slow email delivery down and not actually reject it.

Help! Smtp problems, can't send email

Hi,
Right I have been using Mail version 1.3.11 (v622/623)
for a long time and all of a sudden about 2 weeks ago it starts timing out when sending email. Restarting mail or the computer doesn't change it however it did work once randomly within this 2 weeks!
I have tried a few things like changing the port from 25 to 527 (or whatever it is, can't remember offhand) and even from a different computer. I have tried pinging the server smtp.mac.com from both computers with no luck also.
I haven't bothered with apples help yet as the last 2 questions I had took over 3 weeks to answer. So any help would be fantastic!
I'm using OS 10.3.9 on a 1.5Ghz powerbook, and the email account is a .mac one if that's any use.
Thanks for any assistance...

OK. Finally solved the problem. It is not related to network. I have been having this problem with a number of people on different ISP's.
Here's the scoop. Several ISP's have stopped allowing anonymous relaying on their smtp servers in an effort to improve security. And without warning, a couple of them changed the authentication methods. Initally I dismissed the problem as an authentication problem because the apple mail program feedback says TIMEOUT, not rejected password or ID, which led me to beleive this was a network/port problem.
Some require just a user id, some require id with a password. So, like an idiot I just assumed that since I haven't changed any settings for authentication the answer was not there. But I was wrong. If you authenticate to the smtp server using your mail id and password (should be the same for incoming mail) you should be now able to send. Once I fixed this on all the computers, mail started going through without rejection.
Sometimes it takes a few tries for the mail to actually get accepted, but once you hear that lovely jet sound, you know you've got it.
I'll check back soon to answer any questions you may have.
I'm sorry it took so long to post a solution but other problems have taken precedence.

Since "upgrading" to OSX ML, I can't receive or send email. Why?

Since "upgrading" to OS X Mountain Lion, I can't receive or send emails in my @icoud or @me mail accounts and when I delete old messages in the Inbox, they come back the next time I check the Inbox. oes anyone know why the mail is this screwed-up? I've been forced to reroute all of my mail to my windows Outlook account to receive them.
jrincr

Go to System Preferences > iCloud and make sure your account info is correct, delete the password and reenter to be sure it is clean. Go to Mail and then open Preferences and check the account informaiton for the iCloud account and again, delete and reenter the password for the account. Sometimes the passwords get garbled during an upgrade.

E63, can't send email, AT&T

I have two email accounts on my phone @sbcglobal.net and another, non-ATT account. Using the standard Nokia email program, I've been able to send and receive for quite sometime from both accounts. Now I can't send using the non-ATT address, but the @sbcglobal.net account works fine. I've tried every setting I can think of, but ATT specs cwmx.com as the outgoing box with no password.
I'm not sure if this a result of the firmware upgrade from a few weeks ago, but I doubt it given that I can send [email protected]
Any insight would be helpful as ATT is clueless.

"Delivery Status Notification 500" means that the receiver didn't get the mail. Check your SMTP/POP/IMAP settings and be careful with large attachments.
