Hi, I have sendmail MTA and i use pear:Mail class to send mails through remote sendmail server. Everything was fine till yesterday. Probably nothing changes was made in configs.

At maillog i can see: May 6 12:58:55 xxx sendmail[25903]: STARTTLS=server, relay=hostxxxx.static.xx.xx.pl [85.x.x.x], version=TLSv1/SSLv3, verify=NO, cipher=DHE-RSA-AES256-SHA, bits=256/256 May 6 12:58:56 xxx sendmail[25903]: o46AwtqE025903: hostxxxx.static.xx.xx.pl [85.x.x.x] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA2

and in /var/log/messages: May 6 13:00:17 lilia sendmail[27193]: realm changed: authentication aborted

I use ldap to authenticate users but i used the same script to check mailing on another server and it works there good, only this server behave weird. Packets are deliverd to sendmail server i can see it in tcpdump, but there is smaller packets than on other server which sends emails.

Could you tell me how can i check what is wrong with that?

I'm using sendmail version 8.14.4 on Fedora 15 to send email. My Rails app uses delayed_job to queue up emails.
