Empty email address in "Mailbox size limit exceeded" sent to forwarding addres
Problem reported by Webio - 8/25/2017 at 1:37 AM
Submitted
Hello,
 
Scenario:
- mailbox MAILADDRESS1 - size 25MB and it has been exceeded
- mailbox MAILADDRESS1 is configured to forward mail to MAILADDRESS2 without message deletion
- MAILADDRESS2 is located on live.com domain
- SOME_SPAM_EMAIL is being sent to MAILADDRESS1 and it gets bounce/error: "Mailbox size limit exceeded"
- in moment when SOME_SPAM_EMAIL is being tried to be delivered new email is being created on MAILADDRESS1 with title "Mailbox size limit exceeded" from System Administrator
- when new email is being created also another email is being sent to forwarding address MAILADDRESS2
 
Can someone tell me why notification is being sent to remote forwarding MAILADDRESS2 since message which caused forwarding is simple local notification message? I thing there should be a switch somewhere to keep System Administrator message local.
 
Take a look at logs.

Shouldn't local notifications messages from System Administrator be delivered only to local account and not sent to forwarding address?
 
Another thing is also interesting and probably this is cause of my problems (about this below). Local "Mailbox size limit exceeded" message contains sender "System Administrator" with proper email address from SmarterMail configuration System Messages section BUT as you can see from Delivery log message sent to forwarding MAILADDRESS2 has empty email addres as sender.
 
I'm investigating this because my outgoing gateway has been marked on SORBS list and I'm trying to figure out why and IMHO cause is:
 
empty sender address in message "MailboxSizeLimitExceeded" which is being sent to forwarding MAILADDRESS2 configured in MAILADDRESS1
 
Any comments?
 
Thanks

This is delivery log entries from yesterday for "MAIL FROM:<> SIZE=10" keyword in log. It looks like there is a lot of messages forwarded or bounced with no FROM address which can lead to blacklist adding.
Can someone confirm this issue on your end? I'm using SM 15.7.6400

Can someone at least check your main server delivery log for 
 
CMD: MAIL FROM:<>
? If you have set System Administrator email address there should be no bounces sent with empty MAIL FROM. This can cause you server to be blacklisted.

How does one set the System Administrator email address?

Crap. My mistake. This STILL can't be set for bounce messages. Only place where System Administrator email used to FROM field is Admin Settings -> System Messages but this section does not contain bounce messages.

I literally can say WTF SmarterTools? Even simple entry in mailConfig.xml file would solve this problem.

This has been reported (I know I know this is community forum but c'mon don't you even look here and consider some bugs as ones which you should take care of without support ticket?) here:
