Postfix SMTP SmartPhone

[ericwait]

I have never gotten smtp working 100%. I can send while on the local network just fine. When I am not on the network, I can send mail depending on my location (eg. school network --Works, public library --Doesn't Work). This might just be because of those public networks blocking ports, I don't know.

However, the biggest issue is that I just got a smart phone (Palm Pre) and cannot send mail. Gmail works and imap works to receive mail from my postfix server but I cannot send anything using my server.

Here is what happens when the phone tries to send: (from /var/log/mail.info)

I will attach relevant config files.

Any insight would be appreciated :D

Try to set your debug level higher (in main.cf):

debug_peer_level = 5

This way you may know what is happening.

Also check your "smtpd_recipient_restrictions" settings.
Read postfix documentation.

Well the debug level did not produce anything new :(

But I did go to http://www.debianadmin.com/debian-mail-server-setup-with-postfix-dovecot-sasl-squirrel-mail.html

Where it brought me to look at /etc/dovecot/dovecot.conf

I had auth default {
mechanisms = plain
where they were saying, useauth default {
mechanisms = plain login

After restarting saslauthd, postfix, and dovecot it seems to be working now.

I don't know if I have left myself more open now to attacks. If you see anything that would be, please let me know. I tested for open relay using abuse.net relay checker and nothing.

I guess I shall see.
Thanks
