SMTP SASL Auth Erro

[barney.parker]

Hi,

I have tried to follow the Postfix / Courier / MySQL installation howto, and although i can recieve emails via my new server, i do not seem to be able to send!!!

I have tried to follow the instructions as closely as i could, making the alteration for my IP and DNS info, but i still can't send any emails!

in the /var/log/mail.log file i get...

Aug 14 15:02:15 starfleet pop3d-ssl: Connection, ip=[::ffff:81.133.139.108]

can anyone shed any light on this?

Thanks in advance for any ideas anyone may have!

Do you get any errors when you restart saslauthd?
What's in /etc/default/saslauthd?

Falko,

Thanks for your reply, When i stop and start SASLAUTHD i get nothing, so i assume thats telling me there is no error as such.

/etc/default/saslauthd contains the following settings

START=yes
PARAMS="-m /var/spool/postfix/var/run/saslauthd -r"
PIDFILE="/var/spool/postfix/var/run/${NAME}/saslauthd.pid"
MECHANISMS="pam"
MECH_OPTIONS=""
THREADS=5
OPTIONS="-c"

Intersetingly there is absolutely no problem when i receive mails, so authorisation does work to some degree.

I am using POP3 to connect to the server. Although IMAP is available i am not currently using it.


EDIT:
as an interesting side note, i tried logging in to the SMTP server via telnet. This allowed me to send emails to anywhere!

EDIT2:

If i remove authentication in my mail client, i appear to be able to send mails, but i get a message telling me that the message had an invalid message recipient.

When i check /var/log/mail.log again i get

Now i guess this is happening because you don't want unauthorised users (i.e. spammers) to be using the server as a mail relay, but on the other hand the log does say i had authenticated via pop3, so now i'm confused as to the exact process of whats happening here!!!


I am also getting log messages in mail.info stating...

Aug 16 09:00:09 starfleet postfix/proxymap[4865]: warning: connect to mysql server 127.0.0.1: Access denied for user 'mail_admin'@'localhost' (using password: YES)
Aug 16 09:00:09 starfleet postfix/proxymap[4865]: warning: connect to mysql server 127.0.0.1: Access denied for user 'mail_admin'@'localhost' (using password: YES)

They always come in pairs, and always from postfix/proxymap

i guess this could mean i have a password entered incorrectly somewhere, but i can't seem to find it.

Also, i can log in to MySql as mail_admin, but not as mail_admin@localhost. Does that matter?

Falko,

I searched the forum and found the answer!!!

In the HowTo it seems to miss a single line (maybe not everyone needs it....)

in /etc/default/saslauthd i had the line

OPTIONS="-c"

It should in fact read

OPTIONS="-c -m  /var/spool/postfix/var/run/saslauthd -r"

To be honest i an mot sure why, but i am still learning!!!!!

I restarted saslauthd (stop then start) with no error messages.

All seems to work perfectly now!!!!

Thanks for your help.
