I have just moved to linode and have installed virtualmin to manage it. The websites have moved over and everything seems fine except for smtp.

With a mail client I can get the email with POP but I cannot send anything the maillog shows the following error when i try:

warning: SASL authentication failure: Password verification failed


Please help.

I think i have fixed it after hours of searching around i found:
http://www.virtualmin.com/node/15570

The problem is that my usernames for the email accounts are in format user@domain.com which apparently isnt supported by default by sasl, I thought that as i changed this setting in virtualmin that virtualmin would have sorted this out for me, but apparently not.

I had to go to do the following

Go to:
/etc/sysconfig/saslauthd

At the bottom where it says "FLAGS=", change that line to read:

FLAGS=-r

Then, restart saslauthd with:

/etc/init.d/saslauthd restart

At that point, it should allow you to login with user@domain username formats.


This seems to have sorted it all out, if anything is wrong with this please let me know.
