[qmailtoaster] mail forwarding
Hi, We have an interesting scenario whereby we had to move some users to an hosted solution, though other users, stayed on the internal mail server (qmail) All the users are on the same domain. (i.e. test.com - though pointing to the respective mail server) The reason being, the internal mail users are not allowed to mail out of the company (domain), which the hosted solution cannot assist with. The problem being, the external users should still be able to mail the internal users vice versa. Any pointers ? Thanks --- This email is free from viruses and malware because avast!

How could they be coming from inside your server? Once a user is authenticated to the SMTP server (qmail-smtp or spamdyke), the system will take messages from virtually ANY user address -- including addresses that are not local and/or are not valid. User A connects on port 587, authenticates as us...@domain.com User A delivers a message with a FROM label of: presid...@usa.gov (or some other bullshit address) and TO labels for 100 of your nearest and closest friends QMail queues them up and sends them -- even though usa.gov might not even exist, much less be serviced by your server While initially this may be seen as a flaw, Eric has correctly pointed out that this feature also helps QMT function as a smart-host. Look in your SMTP/Submission logs for instances where the login name/domain don't match the FROM address...

Dovecot doesn't use run files, it uses an init.d script. I don't see how softlimit pertains to dovecot (nor its use of mysql). Raising which softlimit fixes this?
