Can't send emails!

I am a newbie to sendmail and procmail. A week ago I noticed that I couldn't send any emails ( to two of the 3 domains we have) out from my email client on my desktop. The other domain is hosted on a windows box and is working fine. The two domains that aren't working are hosted on a Redhat Linux box using sendmail 8.12.10. The emails to the two domains in question just stay in the outbox and I get a message that says "a connection failure has occurred." However, I can use squirrelmail to get to the server and view the email boxes. However, it appears the emails do come down just can't be sent out because there are never any emails in the accounts on squirrelmail.

The error logs seem to indicate procmail.

I have looked on other forums and the web but to no avail for answers or help. I even increased the file size but there was no change.

Please tell me how to get the ability to send emails out of email client back.

Any help will be greatly appreciated. Thanks in advance,

Randal

mmm....Are you using Sendmail, Procmail, or SquirrelMail?

You may have an issue where Procmail and SquirrelMail are fighting for the email services. I assume sendmail is just your email server, you aren't also using if for an email client ... ?

I have seen this with Postfix and SquirrelMail on a FC install. So, I'd suggest you try shutting down either Procmail or SquirrelMail and see if you get the other sending and recieving.

Hello,

Thanks for the reply. I un-enabled squirrelmail and rebooted the server but I still can't send emails out from my OE for mac email client. Also, I still can't send emails from outside of the domains in question using a webmail program to send them.

Procmail is being used by sendmail for local delivery.

I appreciate your help.
