Suddenly unable to send out email from multiple machines

‎04-12-2009 02:17 AM

We've had nice reliable service since we originally set up with Comcast internet service about a year ago.  Suddenly, starting yesterday, we've been unable to send out email.  Our outgoing server is set up as "smtp.comcast.net" as always.  We've tried deleting, reinstating, restarting machines/router/modem. We've looked into firmware update for our router, but it appears current.  We're out of ideas and need outgoing mail to function (webmail is too cumbersome for general daily use).  Any suggestions are appreciated.  We're out of ideas.

After poking around the forums and following several trails, we solved the issue on our own.  It seems Comcast put a block on our outgoing port, 25, since, as they describe it, there were spammy emails coming from our location.  We actually got an email notification, but it went to our dormant main account.  Anyway, I thought I'd post here in case anyone else ever has a similar problem.  The email guides you through the corrections to get mail up and running again.  But, the short version for MacMail is to set the outgoing port to 587, ssl on, authentication=password, enter your main Comcast id and password.  After all that, shut mail down and restart program.  Good luck!

Glad to hear you got it up and running. These forums contain a lot of information but sometimes it is hard to find exactly what you are looking for. We often hear from people who spent hours searching before finding the answer to their problem. So thanks for posting the solution that worked for you.

 

For others with a similar problem there are instructions for setting Mac email to use port 587 in the email FAQ and help pages.
