Default Virtual users passwords are being rejected? (postfix)

Hi, While trying to get postfix up and running with ISPConfig suddenly the passwords of virtual users are not longer being accepted (previously they just hadn't been able to receive email - though the users on the 'home' server seem to be ok). If anyone has any suggestions they are most welcome! Thank you. Ben

Ok, ISPConfig 2 does not use virtual mail users, it uses linux system users for email and the user passwords are stored in /etc/shadow.

Which is the error message that you get in the mail log when you try to authenticate with a mail user?

Hi Brehm, that makes sense since the host server's user emails are ok. The message is 'Aborted login' (i'm using Dovecot for pop)...

Please post the exact error message from the mail log, not the error message that you got in the pop3 client.

Hi Brehm, thanks for your efforts with this - i was trying to go back to where i had the settings earlier when it worked and i got it logging in now, but back to the old chestnut where email bounces back with a User unknown message (550 5.1.1 User unknown). Can you recommend anything for this?

Curiously, if you send mail from a user account to another user account it works ok. It's only 'foreign' incoming emails that get the bounceback.

The maillog confirms the user is logging in and out ok now.

And, as usual, the @ homeserver accounts are all fully functional. It's the sites not named after the home server that are failing here.

Your help appreciated!

Ben

I narrowed it down a little.

mydestination =/etc/postfix/local-host-names
overcomes a 'relay access denied' error message, and,

virtual_maps = hash:/etc/postfix/virtusertable
enables email to go between users, and from outside users to the home server users... (which are those home server users actually written into virtusertable, rather than linux users)

so it looks like those files are being referenced correctly.. but somehow incoming mail from non local users to @domains other than the hostname are getting bounced back with a user unknown message..... but in the maillog those all users are logging in and out ok with no error messages....

1) Is the email address that you want to send mail to listed in /etc/postfix/virtusertable
2) Please post the exact error message from the mail log file, not the message that the sender gots back via mail.

Hi Brehm,

a) virtusertable looks good, addresses are there and of the form:
name@domain.com user_name

b) in the maillog there's no record of the bounceback email... i just have login/disconnected records

..maybe this is an MX issue. i'm checking it out.
