Hi,

I've setup my postfix mail server successfully using the linode guides. It's working almost perfectly except my users cannot send email using outlook express.

I've done some googling and it seems the problem is related to the fact the LOGIN auth method is not 'offered' by postfix upon EHLO.

220 athena.mammaf.it ESMTP Postfix
EHLO me
250-athena.mammaf.it
250-PIPELINING
250-SIZE 30720000
250-VRFY
250-ETRN
250-STARTTLS
250-AUTH PLAIN
250-AUTH=PLAIN
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN

It just offers PLAIN.

How can I offer LOGIN type, I can't find the right setting

Thanks

OK, found the setting. My SASL is configured with dovecot so I needed to add the following line to the dovecot.conf

auth_mechanisms = plain login cram-md5

I restarted dovecot and looked like it didn't work but then a subsequent reload of postfix picked up the new setting:

250-AUTH PLAIN LOGIN CRAM-MD5
250-AUTH=PLAIN LOGIN CRAM-MD5

Woo hoo!
