I've increased these to 100Mb to see if this will resolve it as per other posts
[zimbra@hostname log]$ zmprov gcf zimbraMtaMaxMessageSize
zimbraMtaMaxMessageSize: 100000000
[zimbra@hostname log]$ zmprov gcf zimbraFileUploadMaxSize
zimbraFileUploadMaxSize: 100000000
unfortunately we're still having issues with a message larger than 10mb transferred from an IMAP account to a Zimbra IMAP account.
however, I am able to send an email containing an attachment >10mb without any problems.
I also don't see anything in maillog or zimbra.log when a message is moved...
The common error the users see in their client is
mail server responded [TOOBIG] request too long
Thanks for your time
