My mail.app suddenly stopped sending emails. I receive everything, but cannot send out anything. Apparently, it's a fairly common problem with mail. I think I've tried everything. Can anyone help me out, please?
First thing I would try would be to quit Mail, restart it, delete the email account in prefs, then re-enter the account settings and see if that works. That is BTW the very first thing Apple had me do when I had a similar problem.
Thanks, SINC. I've tried this, but unfortunately, no go. I keep getting the message that smtp server is offline. I called my provider but all they told me is that they encounter this problem with MACS all the time and that nothing could be done about it. I find this hard to believe. My Entourage works fine. It's just Mail.
You haven't mentioned which Mac you have (desktop? Laptop?) and whether this problem occurs in one place or various (home? cafés?)
As a laptop user, I sometimes encounter problems with SMTP when connecting from different locations.
Problem 1: each Hotspot has its own / different SMTP server, depending on the provider. If you connect to a Rogers hotspot, but try using a Bell SMTP server, it probably won't work. You need to reconfigure your mail client to send mail using the proper SMTP server - and if it requires authentication, you probably can't.
Solution: use the Webmail interface to your email (if it has one) or - the solution I went for - sign up for Dot-Mac (or Gmail works too) which uses its own SMTP settings.
Problem 2: Which Send Port? Sometimes port 25 is blocked from sending mail (it was the default send-port on Eudora, for example).
Solutions: In the settings you can specify port 587 (Read this article and this article) which should allow you to send mail.
However - if it's a problem at home, with your own ISP, then that ISP's tech support should have a solution beyond saying they run into this all the time "with Macs".
Thanks for the response. I have a MacBook running Leopard. I've had the computer for almost a year, using it across the country and even in the US. Never had a problem until last week. I've tried different port settings. Same thing. I'm really dumbfounded.
Since it works in Entourage and not in Mail, the issue is with some setting somewhere, even maybe some firewall or some proxy you have running. I doubt your ISP is blocking (inadvertantly or not) the application itself, since it uses the standard SMTP protocol which doesn't care what app you're using.
I must say too that your answers are very vague "I've tried everything" doesn't mean much. Maybe screenshots of the error messages you get, screenshots of the settings both in Mail and in Entourage (blank out your email address/name and such), maybe the logfiles (Utilitiies -> Console , I believe) can shed some light too.
Basically, the more information you can provide, the more we can help, and you might just end up helping yourself too
