We're running SmarterMail 14.0.5661.  Recently I noticed that, while checking on the activity of an account that triggered our lowest abuse notification, I saw entries in the delivery log (not abuse as it turns out) but nothing in the SMTP log for the time in question.  At first I thought perhaps he used webmail, but upon logging into his webmail via impersonation, I found nothing even close the time period in question.  What I did find for that time were login entries for his account in the Admin log, but in the SMTP log, nadda. 

 

My understanding has always been that, regardless of whether it's an email client program on a PC, tablet, or phone, and regardless of whether the program/device is using POP or IMAP for retrieval, sending is still done via SMTP, isn't that right?  If that's the case, why would there be nothing in the SMTP log for that session??? 

 

Thanks guys!
