Could not connect to SMTP host

Hi there,
Easy WP SMTP works most of the time, but sometimes mails are not send. Looking at the debug-log, I find entrys that look strange, but that don’t help me to see, what did happen, here is one of them:

`CLIENT -> SERVER: STARTTLS
SMTP Error: Could not connect to SMTP host.CLIENT -> SERVER: QUIT
SMTP ERROR: QUIT command failed: M?I?A?.?n?????J??P??Q
*?n??fx?W??0?C??σI-??g(.W?)?pH?Z>D????7R???d?yZ?#?0?O??3Szv?????????x5?,?U?
??;?2?E?:?L??0,????A??Em?P?C??k??’??{N???im????.&tIM<x??;w!?2{e
q=??Z????>??<??Ne?????oo?;?V7??.?? wd???? ???b?d?<p??-?????%8??{R???QO?j????nb?D?%?}YIMs??'?F

There are other entrys above and below this, that are correct.

Is there any way to see a timestamp for the entrys in the debug log? This would be very helpful to synchronize this with the logging of other plulgins or our mailserver.

Best regards

Uli
