Post subject:  Only PLAIN LOGIN?
Hi, I've just completed the Postfix installation and when I get to do the "ehlo localhost" part I get this in the response:

Code:
250-AUTH PLAIN LOGIN
250-AUTH=PLAIN LOGIN


Is this correct? The tutorial shows:

Code:
250-AUTH CRAM-MD5 NTLM PLAIN LOGIN DIGEST-MD5
250-AUTH=CRAM-MD5 NTLM PLAIN LOGIN DIGEST-MD5


Also, it states to set the reverse DNS to fully qualified domain name you assign as the system mail name, but I can only set it to the domain name rather than host.domain.com, can anyone tell me why?

Thanks,
Luke.

Plain logins are required in case you do not store plaintext passwords in your database (i.e. UNIX password) and you do not have stored all possible hash variants (IIRC possible with MySQL). See documentation, it should be described pretty well.

As for PTR record, check whether your FQDN really points to your IP address and whether it had time to propagate itself (usually few hours).

Erm, I set up my 2 domains as per the instructions on the site, my hostname is "beast" and the domains are feastiality.com|co.uk. I didn't put anything pertaining to the hostname in the set up of the domains in the control panel.

You need to add A record of "beast" to your DNS zone.

dig beast.feastiality.com. shows me there is none and therefore Linode won't allow you to set such PTR (Reverse DNS) record.

Make sure you can see something like that in your DNS Manager:
Code:
A/AAAA Records
Host Name    IP Address      TTL      Edit    Remove
             74.207.226.---  Default  Edit    Remove
beast        74.207.226.---  Default  Edit    Remove

Also consider forcing TLS/SSL with plaintext passwords.

I have the same problem with PLAIN LOGIN. I tried googleing to find how to generate all password hashes in mysql or how to force TLS/SSL with plain-text passwords but my google-fu failed me. Can anyone please point me to the right direction?
