Tony, This is an issue with a signature in the daily clamav database update. It affects servers running on CentOS 5 due to the fact that they have a version of pcre that clamav can't link to properly to form the database. CentOS 6 and 7 aren't affected. Supposedly the clamav folks have built a version of daily that won't break mail delivery, but I don't know for sure. If you turn off clamav in simcontrol and recompile qmail cab, then mail delivery will resume unaffected. You won't have virus scanning on incoming mail, but at least delivery will work.
Check the clamav mailing list: lists.clamav.net/pipermail/clamav-users for a better explanation. They won't support clamav 99.3 on pre-CentOS 6 installs, so looks like it's finally time to upgrade those old servers, eh? > On Mar 3, 2017, at 10:26 PM, Tony White <[email protected]> wrote: > > Hi folks, > This is Tony sorry to have to use a Yahoo acount but my mail server > broke this morning at 8am. > Submission and SMTP servers are now responding to connections > with this error... > > qmail-smtpd: qq soft reject (mail server temporarily rejected message > (#4.3.0)) > > I have made no changes so I am at a loss to the issue.
