Mail won't send. dotMac SMTP server Issue?

Using 10.4.8 and Mail. Mail won't send. Says to try a different server, but I don't have anything other than dotMac. Others are having the same problem. Anyone know a solution?

Who is your Internet Service Provider? What is your current SMTP setting?

Mail won't connect to SMTP server when using wireless instead of ethernet

I receive the following error message ONLY when I am online via a wireless connection, but not when I am online via an ethernet cord:
*This message could not be delivered and will remain in your Outbox until it can be delivered. The connection to the server "smtp.XXXXX.com" on port 2525 timed out.*
(note that XXXX is just the name of my mail server that I've removed for security reasons)
I am able to receive email fine regardless of whether I'm using a wireless or ethernet connection.
Any thoughts? I've occasionally run into this issue before (at coffee shops and such) and think it may have something to do with the type of wireless connection (too weak, low security, other?) I'm particularly stumped about this one though since it's simply the wireless network at my college which has worked fine in the past (though perhaps they did change something?)
Thanks!

That's because the internet provider whom you are connecting to via wireless is blocking that port/server address as a security measure.
Unless you have an account with whom the host is, you wont be able to send emails...
you could try setting the outgoing port to one of the following you could have some luck, no guarantee's though...
21, 25, 5521, 5525, 7721, 7725
hope that works

Mail won't send outside of server

Hi there,
Suddenly my Mail decided that it doesn't want to send to receivers outside of my server. For example: my email address ends in mppc.net and I can send messages to folks with the mppc.net address, but not to anyone else. I have checked outgoing mail preferences and everything seems in order (to my eyes). My server requires authentification, and I selected that. But nothing changed.
I deleted the account and recreated it and still no success.
Can anyone help?

I haven't spoken directly with them, but I did speak with our IT guy and no one else seems to be having the problem. I'm the only Mac in the office and our guy doesn't really know Macs, so he's not very helpful.

Mail won't send but Connection Doctor says smtp account OK.

Mail won't send but Connection Doctor says smtp account OK.
I can receive mail but can't send it from Mail 3.5. Same problem on a wired G5 and on a wi-fi MacBook (using the same account), so not hardware related. Worked fine 'till today - I didn't change anything in between times. Incoming mail no problem. Tried mail rebuild, keychain first aid, deleting the account, repair disk permission - doesn't help.
Mail's connection doctor says "smpt.xxxxxx - connection to server succeeded, no login required."
Anybody any ideas? Thanks, N

Been having the same problem for a few weeks now. This has been working just fine, and all of a sudden - nothing. The update to 10.5.6 didn't do anything to fix this either.
I've spent numerous hours on the phone with the Apple support. Seeing as the two other accounts that I have configured work with no problem, they say that this is a problem with the provider which is also the ISP. I then called the support line for the ISP and informed them of this and they say that it's a problem with the software.
Interestingly, if I send a message to somone with the same ISP, the message will go. But I can't send a message outside of the provider. Does anyone else have this problem?
Also, from another forum, they suggested rebuilding the LaunchServices database. The Apple support didn't see what that would do. But I tried it anyway and the problem still exists.
Another intesting thing is certificates. It's only happened twice, but I've received the message saying that Mail can't verify the certificate XXXXX which validates the identity of the smtp. Anyone else get this? I thought perhaps I could delete the certificate and it would magically reappear. But when I go into KeyChain, the certificate is listed only under System Root and I can't delete it.
ideas?

My mail won't send...

Hi,
My mail won't send on my laptop. There is spinning next to "Send" but the message remains in the outbox.
I deleted and readded all email accounts. This did not solve the problem.
I started a chat with Apple Express support and they said that Lion doesn't support Apple mail so they couldn't help.
I can send via webmail.
I can receive mail.
One error message I receive after it has tried to send the message for awhile is:
Connections to the server “mail.smtp.me” on the default ports timed out.
Select a different outgoing mail server from the list below or click Try Later to leave the message in your Outbox until it can be sent.
My password and username are correct; however, the following error message appears in the Connection Doctor window:
Trying to log in to this SMTP account failed. Verify that the username and password are correct.
Does anyone have a real fix for this issue-it doesn't happen all the time, but has been happening every day for the past week and I need a reliable program to send mail.
Thanks.
lsb

Becky,
Check your smtp server and check if your password is added. After ungrading Mail might have lost the password.

Hello Bill,
Who is your eMail provider, the part after the @ sign?
In Mail's Window Menu, choose Connection Doctor, any red dots for status, if so what is the message?
Then click the Show Details button & Check again.

TS2756 Tethering. iphone5 email smtp server issue

I have an wifi ipad 2 and an iphone 5 on EE 4G network. I have configured the iphone 5 as a wifi hotspot, I can connect my ipad, browse the web receive emails etc. the problem comes when I want to send emails, it keeps telling me there is a network error. I know this is not true, I have a feeling it has something to do with SMTP outgoing server, possibly the port number? The incoming servier is port 110 and I have outgoing set at port 587 but think it could be some other port or some other issue. Would appreciate any help anyone can shed on this issue
Richard

My problem has been resolved.
Regarding that, probably you should check with SMTP server admin.
For me, the shcedule was success but didn't receive mail. I think the SMTP server admins cleared any firewall filters.
Not sure. Please check with your SMTP server admin.

Mail won't send mail when in wireless mode but works fine when wired

Ok, this happens all the time. I have several pop email accounts, all of which work fine when I am hooked in to an ethernet cable, but Apple Mail won't send any of my outgoing mail form any of my accounts when i'm am working wirelessly.
I always get a message like:
Cannot send message using server smtp.name.net
I try to switch servers and I cycle through all of them, getting them same message, followed by things like:
The server response was: 5.1.2 Bad or missing RCPT domain k39sm5757680wah
Any advice.

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.
You may use “network locations” to more easily switch between network settings if necessary, as described here:

TS3276 Mac Mail won't send emails with signatures

My Mac Mail won't send emails with signatures. I get the "whoosh" sound and they show in sent mail, but the recipient doesn't receive them until I take off the signature and resend the email. Without a signature, it is received. It never used to be a problem, but started this past month. Please advise!

Did Earthlink have you try using their authenticated SMTP server?
If not, try changing Earthlink's SMTP server settings to the following:
SMTP Server: smtpauth.earthlink.net
Server Port: 25 or 587. Assuming Earthlink is your ISP, 25 should work.
Use Secure Sockets Layer (SSL): Off or not selected.
Authentication Type: MD5 Challenge-Response. Not sure if this authentication type is available with 10.2 and if not, select Password.
User Name: Your entire Earthlink email address.
Password: The password for your Earthlink email account - the same password used to check the incoming mail server for new messages.

Mac Mail won't send .mac mail

All of a sudden Mac Mail won't send mail from my .mac account through it's mail server even though the MobileMe sends mail just fine.
Anyone know what may be up?
I hate using the mobile me mail.

I experienced the same problem--unable to SEND mail using MobileMe server. Changed to port 587, now seems to work (cross fingers).
I also noticed that I cannot change the incoming mail server name from "mail.mac.com" to "mail.me.com." When I try to change then save, it reverts to "mail.mac.com."
By the way, under the "Advanced" menu, can anyone explain "IMAP Path Prefix"? It's blank by default, I gather. Why might someone use a prefix here? Also the default port is 143 and the "Use SSL" block is unchecked.
Merely curious.

Apple Mail won't send invitations when initially closed

I just started using iCal to send invitations for appointments through Apple Mail. When Apple Mail is opened already when I create the appointment and click Send in iCal, it works fine. The mail is sent and delivered to the appropriate address.
But if Apple Mail is closed initially, the application starts and the invitation is queued up in the Outbox but is never sent. I can manually open up each invitation in Mail and send them individually, but why is the behavior different? Whether Mail is opened or closed when I send an invitation, it ought to deliver the invitation automatically. By not being sent, I may not realize the invitation hasn't been delivered, making the process very error-prone. Is there a way to guarantee the invitation actually gets sent without having to check the Outbox every time?
Is this an iCal bug or an Apple Mail bug? I saw no settings in Apple Mail for sending messages at shutdown or any other setting like this. Instead, these invitations may end up being buried in my Outbox for a very long time before I notice and by then, it may be too late.

The most recent OS is currently OS 10.8.3. Your system profile confirms you are still using Mac OS X (10.7.5). If this is incorrect, please correct your profile so that you will get the correct troubleshooting suggestions/solutions.
Also, post in the OS/Mail forum of whichever OS is currently installed on your MBP. It's where the OS/Mail expert helpers hang out at.

Mail won't send without Connection Doctor having to be launched.

Mail won't send without Connection Doctor having to be launched. After running Connection Doctor, it will send, so settings all must be ok. But 15 minutes later, I need to "check again" to send mail. I read previous posts on this from a few years ago, but my laptop is running Lion.

Try just watching the "Activity" window to learn what is happening to your mail - I have found it to be most enlightening.
