Hallo to all,
I've upgradet to version 1.4.7. from 1.4.3 and now its not possible to send mail neither with nor without encryption. Webmail says authentication fails, telnet connection on port 25 is ok, ehlo answer looks god but rcp to does it not...and all mailclients say, that authentificantion fails...
Receiving runs well - affected all my servers which run imscp. One of these hosts som custumer mailaccounts and they are not very amused...:(
I have no Idea what is to do.
Neither auth.log nor mail.info nor mail.log gives a hint
System is Debian Jessie 8.8, it is a vServer
What could be wrong now?
