Mail without a subject or sender
Hello
*
I have a mail server (postfix + dovecot + amavis + clamav + mysql + dkim) on Centos 6.8. Last I updated the PHP version 5.6.26. Since that time I have problems with the mail. Users see in squirrelmail e-mails are missing sender or subject, or both things at once. This is not always the case but there are times. The result is their inability to read.
*
I looked maillog but nothing alarming was not found. Everything looks normal. I can not deal with it. Postfix and dovecot still operate normally. Mail is sent and received. I bet on amavis + clamav but my experience is too small to insist. What do you think? We care about the time, so please any advice or clue or anything that could steer me to solve this problem.

Regards
mariusz
