Hi all, Once again thanks for the nice howtos. I have an issue with this one. The welcome mail never arrives in the brand new mailbox, so I get Squirrelmail errors when I try to connect (ERROR: Could not complete request. Query: SELECT "INBOX" Reason Given: Unable to open this mailbox.) In /home/vmail, the domain_dir is created, the username_dir too, but then only .Sent, no other directory. I created an A record in my DNS and it works great, I receive mails sent via mailx on another autonomous mailbox. The mail logs shows always the same message : May 5 16:41:44 sunsqueeze postfix/smtp: 162AF1543D8: to=<[email protected][email protected] 18.104.22.168 is my router/fw public address. sunsqueeze.morenetworks.net is the name of the machine (/etc/hosts ok, and ping response @ local address)... I use port forwarding rules to redirect traffic to internal servers. Sounds like the server doesn't want to relay messages to itself ? Any ideas ? Cheers, S.
