Hi,
We were working without any mail issue till we were on UTM version 9.209-8. To invite our badluck, by mistake (without looking at known SMTP related TLS-no shared cipher issues of 9.210) we upgraded to 9.210. So selective mails started to reject due to TLS/ certificate issue).
Emails are now a days critical, the whole office started to call IT.
As 9.304 was also released for genral use, instead of manually fixing the TLS issue (as per the steps mentioned on certian sites) we decided to upgrade to version 9.304. (where it was mentiond that TLS issue is fixed)
Now 9.304 has resolved the bug of 9.210 (TLS-no shared cipher) and we do not see any rejection in SMTP log related to no shared cipher. But we are facing a more critical issue and the problem is we are unable ot trace it. Now some mails are missing but no trace in the logs. Initially we thought some secific sender but now more and more complains. It is not that mails are not coming, in last 24 hours around 5000 mails are there in the SMTP log. but still there are mail sent but no trace in the SMTP log.
Any suggestion how we can trace the issue. We are in real trouble and if nothing works we think of going back to 9.209-8 as a last option.
Regards,
Mohsin
