SMTP Server down/Outgoing mail stopped working

Wednesday morning, July 1, my outgoing mail stopped working. I'm using Mac Mail on OSX Yosemite. Incoming mail is working just fine. Outgoing says it can't make a connection.I have it set as smtp.comcast.net port 465 Use SSL is checked. Password authentication. I have rebooted the router (which came from Comcast). I've tried unchecking password authentication, chaging to port 567. Nothing works.

No.. Still isn't working. I tried the .plist edit solution (which frankly, seemed like a bad idea) and deleting all the comcast entries from the keychain. I was prompted for a password when receiving mail, but sending mail is still not working.

Outgoing Mail stops working

My parents have an iMac with 10.3 and have a pop account with PraireWave. Mail has worked fine for over 1 year. Recently a problem has developed where new mail will not send. Restarting the machine solves the problem.
Any ideas?

Bryan,
Welcome to the Discussions.
Is it possible that PraireWare has changed the name or authentication for the SMTP used as Outgoing Server? Many ISP are making changes in this regard, as they fight SPAM. Sometimes the old method is honored, for a time, and may be inconsistent during the transition period to the new SMTP or new authentication requirement.
More info, please.
Ernie

Finding proper smtp server for outgoing mail

I added my school's e-mail account and i can receive mail just fine. I'm having trouble finding the right server name to send mail from that school address.
Is there any general rule for what a server should be called, or is it specific and i need to find out from the school?

There are not har and fast rules about naming of SMTP servers. Naming convention usually results in 'mail.yourdomain.com' or 'smtp.yourdomain.com' but the naming is just a preference of whoever set up the server. You generally need to ask your mail server administrator for the name and/or access information. There are some definite caveats that are likely going to affect you however --
- Most mail admins do not allow SMTP access to their servers from off their network unless they've configured/enabled SMTP Authentication or some other way of verifying that you're really who you claim to be. Again, your mail system admin can let you know if they support this and how to configure Mail.
- It is almost always acceptable to use the SMTP server of your ISP (comcast, bellsouth, etc) regardless of the POP/IMAP account you are checking. You do not need to use your @comcast or @bellsouth email address to send through those servers.
- When in doubt about server settings, mail server admins would generally be happy with you contacting your local helpdesk or admins to be sure you're using the correct settings.

Exchange server setup on Mail stopped working recently

Hello,
I have an Exchange mail account, that's setup using a POP account type. This was working up till just two days ago. Now, every time I try to access my Exchange email account on Mail I get this error:
"The attempt to read data from the server "xxxx.xxxx.com" failed."
I've tried deleting the account and recreating it...I get the same error. A few notes:
1. When I recreate the account, the setup process seems to be able to connect to the server (trying incorrect login credentials results in an error, correct credentials do not return an error). As soon as the account is created, I get the above error.
2. I have this Exchange account setup in Entourage and on my iPhone and it works in both of these places.
Any help or suggestions would be greatly appreciated.

Not certain, but this can fix myriad Mail problems...
Safe Boot from the HD, (holding Shift key down at bootup), it will try to repair your Disk Directory while the spinning radian is happening, so let it go, run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, then move these folder & file to the Desktop.
Move this Folder to the Desktop...
/Users/YourUserName/Library/Caches/Mail/
Move this file to the Desktop...
/Users/YourUserName/Library/Mail/Envelope Index
Reboot.
If that doesn't do it and you can afford to redo all your Rules, try these & reboot...

Mail error "Verify that you have addressed this message correctly. Check your SMTP server settings in Mail preferences and verify any advanced settings with your system administrator.Select a different outgoing mail server from the list"

The Mail application has suddenly started giving error:
"Verify that you have addressed this message correctly. Check your SMTP server settings in Mail preferences and verify any advanced settings with your system administrator.Select a different outgoing mail server from the list"
It was working fine till yesterday, suddenly it stopped. I have 3 email accounts configured here, 2 are on exchange servers and one yahoo. Connection verification works and shows all servers as green.
Any inputs?

I had 3 accounts, 2 ms exchange accounts and 1 yahoo. After removal of yahoo, everything is back to normal.

Mail: other smtp options for outgoing mail?

I'm sure many of you have switched over to the iPhone from a Blackberry so you'll know what I'm about to talk about. How do I change the "from" field of any outgoing mail? When you setup a mail account on a Blackberry you only need an email account, username and passwd. I'm not sure but I think Blackberry uses the same smtp for all outgoing mail and just changes the "from" field of the message to match your account right? You don't enter any type of smtp or pop3 information when you set up a Blackberry.
Here's the problem: School email is set as an imap server but there is no internet smtp server, only an intranet available smtp. If your on campus you can use the campus smtp but if your not you need an external smtp. Setting this up on a Blackberry is as simple as email, user and passwd. (there are no server settings) On the iPhone you need server settings but there is no smtp server available! Putting in a gmail or yahoo server will work but then your sending from that smtp and any replies go to that account. I need to be able to send through the gmail or yahoo or whatever smtp and still let the recipient reply to my school account. Anyone got a work around for this?

I upgraded the software on my Time Capsule and outgoing mail stopped on my Mac Air

Hi
I upgraded the software on my Time Capsule and outgoing mail stopped on my Mac Air
My colleagues are using my Time Capsule on their Mac Air (with Lion OS System) and Dell with MS OS System.
I am on OS X 10.6.8 and was sucessfully using SMTP for outgoing mail .... after my update for the Time Capsule, Mail on my Mac Air stopped
Why?
Thanks in advance
Jan

Hi Garmulewicz,
Can you tell us a little bit about the SMTP service? What port is it set to use? Authentication SMTP? Have you tried manually sending over Port 25, 587 or 465? If you bypass the Time Capsule can you confirm that SMTP traffic still works behind the same modem?
I've personally never seen an update break SMTP, that would imply that the update somehow is blocking the port where SMTP is occurring. What if you configure a personal GMail account or something else, does that work?

Server rejects outgoing mail from PC's but will send mail from Macs

I am having a strange problem with outgoing mail all my mail clients are pointed to the server as smtp server. All mail from Macs are delivered without any problems but mail from PC's are universally rejected and I can't understand why. I did not have this problem with 10.4.11 and we do not authenticate. Here is the reject message:-
+Your message did not reach some or all of the intended recipients.+
+Subject: hello 16:34+
+Sent: 26/08/2010 16:34+
+The following recipient(s) cannot be reached:+
+'user@cp-lighting..*' on 26/08/2010 16:34+
+504 5.5.2 <PHILSPC>: Helo command rejected: need fully-qualified hostname+

This should help:

Will work without authentication as long as your network range has been entered into the postfix settings.
That said, you should require all your clients to authenticate to send through your server.

How can I control SMTP server list in Mail?

I've seen a lot of discussion about e.g. deleting servers, but it often includes smug replies like "click the delete button" when there is often no such button. I have found a possible 'get around' to this particular problem by changing the server data to something that doesn't exist, save that, then select the server again from the list and hey presto, there is now a Delete button you can use. But again, that is not the full story because if that server is used as the primary server for any other account, you cannot modify the data.
Not only that, but you CANNOT simply swap servers so that e.g. an account uses one of the other servers as its primary server. Unless I'm missing something major here, it is NOT possible to move servers. You can change the data for the server to be exactly the same as another server, but that just means you now have an identical duplicate. Once a server entry has been created, it is an independent data entity.
So I seem to have several problems here.
1. A server cannot be deleted if it's in use as a primary for any account.
2. Servers cannot be moved, i.e. swapped between 'Primary' and 'Other'
3. Simply editing the server data does not 'merge' it with any other entry that may have the exact same data.
4. When creating an account, you cannot pick the outgoing SMTP server from the list of ones already created. Simply entering the same data as one that already exists may use that existing server, but may create a new duplicate. I have seen both of these occur and once there's a duplicate, you cannot get rid of it.
I want 3 accounts to all use the same 'Primary' server and also have the same 'Other' server. IOW, only 2 actual servers. After the first 2 accounts are created, that's what I have. Somehow they seem to be able to 'share' the same servers. But when I create the third account and enter the same data for its SMTP server as the others use as their primary (i.e. exactly the same process as when creating the second account), for some reason it does NOT use the existing matching server and I now get a third server created. I simply cannot get around this since whatever I do, each of the duplicates is used as a primary and so cannot be deleted. If I could swap them around so that the third account was using another account as its primary, then I could delete the duplicate and all would be well, but as pointed out above, that's not possible.
I'm hoping that I'm simply wrong about all this and it is actually possible to do what I currently believe it impossible. Can anyone explain how to actually control this server list?

i have exactly the same problem using 10.9.4 - did you ever get a reply?

Mail stopped working

I have had this iTouch for 10 days now. I have version 2.0.2(5C1) and everything was working perfectly until I connected the iTouch to my Mac Powerbook today. Then, Mail stopped working altogether. Send or Receive is not working. I just see a "Checking for Mail..." sign at the bottom of the screen when I go into an Inbox (gmail, me or company email). All other apps seem to be working fine.
Any suggestions (other than to throw this wonderful POS out?) I actually do mean "wonderful" because I did love this until today. Maybe the "Mobile me" is screwing this up....thoughts?

Hi CInglez ,
Do you care to share what the solution was? I thought when you ask a question on forum and hope that people reply, should'nt you update if you have resolved the problem.
Anyway, you are not obliged to anyway.
Just wanted to update that i was facing the similar issues.
OCS version: 10.1.2.4
OS: SuSE 9 Update 3
Issues: Could not telnet on OCS server localhost on port 25, even though the listener_es and all email processes were running.
Solution: set the stack size to 512
Step by step instructions to resolve:
1.logon to the terminal running ocs apps server as oracle user
2. run ulimit -a and you will find that stack size is set to unlimited (assuming you have it to default)
3. set stack size to 512, by running the following command:
ulimit -s 512
4. run ulimit -a and ensure the value for stack size has changed.
5. from that same session run: $ORACLE_HOME/opmn/bin/opmnctl stopall
5. Now start all the process from that same session: $ORACLE_HOME/opmn/bin/opmnctl startall
This has resolved the issue for me, to set this parameter permanently please follow the metalink note # 395083.1
Hope this helps.
Thanks,
Dipak

Mail stopped working - closes within 2 seconds

As of 2/14 my iPhone mail stopped working. I lauch the application, it opens briefly and immediately closes. I link to Road-runner through Outlook on the PC and have MobileMe for push syncing.
After completely reinstalling the email accounts, MobileMe, etc. the problem persists. It opens, now appears to be searching for a connection (a first) then shuts down.
Any ideas?

I had this same problem yesterday happen all of a sudden. My iphone is less than a month old and email has worked fine. I had two mail accounts on my phone, one mobileme & one gmail for work. The phone would seamlessly give me my email for both accounts, I thought it was pretty sweet. Then yesterday, I went to open my email and it would open for 3 seconds and close. If I switched from gmail to mobileme, it was sometimes staying open longer, but would still close. I called tech support and they had me reset the phone twice and finally restore the phone from backup. That didn't work either. Unfortunately, the only thing that finally worked was to delete the Gmail account from my phone. Now mail is working just fine. I plan to go to the Genius bar so I can put my Gmail account back on my phone.

Mail stopped working on Airport Express wifi.

Using Airport Express. Suddenly, only Mail stopped working on my iPad & iPhone, using my home Airport Express. Other internet site work. Mail works on different wifi network. I deleted Yahoo Account in iPad Settings. Re-entering the Yahoo Account gives the msg "IMAP server 'apple.imap.yahoo.com' is not respondig. Check network connection ant that you entered correct info in 'Incoming Mail Server' field.

Had the very same problem with ATT DSL and mail @ my domain. Tried everything including pestering the crap out of my hosting service. Turned out to be AirPort Extreme firmware version 7.6.4 (the latest). I downgraded with Airport Utility to 7.6.3 and all is fine.

Mail stopped working after replacing primary HD

Apple Mail stopped working after replacing and restoring the Main Hard Drive in the upper bay. Internet connection is good, and the Mail client troubleshooting (Comcast) was no help. I can start the App, but it does not retrieve or send mail through Comcast anymore. I have a MacBook Pro with the same settings and Mail works fine.

Thanks for replying.
This is odd because my PowerMac G5 with Leopard Mail cannot receive or send email. Connection doctor is showing all red dots on every email account with Comcast (BTW, GMAIL accounts okay). On my Blackberry, and my MacBook Pro (Lion), the setting are all the same, passwords, etc., and the later two have no issues. I even created a test Administrator Account in "Accounts" in System Preferences on the G5, logged into the Test Account and tried to create a new mail account with the same settings, and yet during the set-up (Welcome to Mail), I get an error message that says Mail cannot log into Comcast's POP server with the current settings. I have also tried changing passwords, no help. Also the usual disk repair, permissions, motherboard resets, zapping PRAM, etc.
Out of ideas...
Thanks for any help...

Try to reset your ipad and/or force quit the mail app
Reset
Hold down the sleep and home keys for about 20 seconds. When you see the silver apple, let go and let it reboot. No data will be lost.
Force close an app
Double tap the home button. When you see the app previews on the screen scroll sideways if needed to get the preview in question on the screen. Flick that preview up and off the screen to close the app. Single tap the home button or home screen preview to exit the mode.
