Aliasdetourhost & mailMsgQuota
807574Jan 17 2005 — edited Feb 11 2020Messaging 5.2 patch2 hotfix 2.03 on Windows 2000.
I need to do an Antivirus scan on all the mail traffic , and i'm trying to use the new keyword "aliadetourhost ".
The mails accepted by the Messaging , are sent to the AV defining a channel tcp_scanin, are re-accepted by the Messaging on the channel tcp_scanout and sent to the final recipient.
Normally the mails flows correctly and are scanned by the AV system.
I have a problem with the mailMsgQuota, that in my envirenments limits the mail size to 2 MB:
when I send a mail more than 2 MB, it passes through " Messaging > tcp_scanin > AV > tcp_scanout " and only at this level is verified and then refused with an SMTP error 552 : exceeded storage allocation.
At this point the AV is not more able to return the mail with the error to the sender, bacause also the return mail is larger than the mailMsgQuota.
How can I workaround thei problem ?
Many thanks!
