Hello,
Since 3 weeks, some customers can't retrieve their messages (Outlook / POP3) for one or two hours (
the window asking the user name and password is displayed)... and and then everything returns to normal use.
All is ok with server (Plesk 12.5 / Postfix). The only thing we see in the maillog file is :
Mar 2 13:36:06 servXX postfix/smtpd[9690]: connect from unknown[x.x.x.x]
Mar 2 13:36:06 servXX postfix/smtpd[9690]: warning: SASL authentication failure: realm changed:...
SASL authentication failure
