I am new to sendmail/systems administration. I'm running a dedicated server, and I think I've finally got sendmail working more or less the way I want: I can send and receive emails. However, when I try to send email from some domains to my server, it never gets through, and I get messages like this in my logs:
STARTTLS=client, relay=somesite.com., version=TLSv1/SSLv3, verify=FAIL, cipher=AES256-SHA, bits=256/256
Any ideas about how I can fix this?
Thanks in advance,
Thanks for the comment -- looks like you're gonna be the guy to help me sort out all my Sendmail problems ;)
The sender is my main website, which is a shared hosting setup run by guys who know what they're doing, so I think the problem is on my dedicated box, especially since I don't have problems sending mail to any other domain with my main site.
I thought maybe I had a problem with STARTTLS confiugration, so I enabled the following lines in my sendmail.mc file:
(they were commented-out by default). However, this didn't really seem to help anything -- I have a feeling maybe my certificates are not set up right. Could you tell me how to set this up? If I'd have to buy a certificate, I'd rather not -- could I just disable STARTTLS ?
BTW, I am running RedHat 9
Thanks again for the help!
