postfix + imap, can't send mail from thunderbird...

[cerealito]

Hi, I'm quite familiar (generally) with gentoo now, but i'm kind of confused with the setup of my mail server...
I'm using postfix, and i woluld like to have mail for local (real) users. I want to have client and web access (thunderbird, squirrelmail?). I've red the how-tos but i'm kinda lost somewhere at configuring courier-imap...

Mutt works fine sending and recieving mail. I'm running courier-imapd-ssl and i can get email from the maildir using thunderbird. My problem is, i can't send mail to the outside world (outside my domain (unam.mx)) WHEN using thunderbird. The client doesn't complain though, but no mail is ever recieved. The logs are quite long, and in fact, i don't know if it's a problem with postfix or with courier-imap, or maybe even a config mistake in thunderbird???

Have some one else had this problem before?

It's hard to find a configuration-error in the middle of nowhere.

If receiving and sending mail with mutt "works fine", then there is quite surely something wrong with Thunderbird.

You have to specify the SMTP-server for each account seperatly. Each with its own user/password. Have a look at Thunderbird's "Outgoing Server (SMTP)" respectively "Server Settings - Advanced".

If this does not do the trick, then the log will be of great help here.
Especially when setting "smtpd -v" in postfix's master.cf (the first line not commented).

But as long as one client (mutt) works fine, I don't think it has something to do with your courier/postfix-configuration.

HTH and Greetings

Ok, I haven't changed anything, not it thunderbird, not in my server...
The thing is, when i had this problem, I was testing outgoing mail sending to my own account at hotmail.com.
I've just tryed with an account at yahoo.com and... it works!
In fact, i've just realized i can send mail from mutt or thunderbird to yahoo.com, yahoo.com.mx
free.fr and universia.net.mx...
could this be a hotmail problem??

What was the actual symptom of "not working"?

Our mail server here was having a heck of a hard time talking to HotMail yesterday, lots of timeouts and terminated connections. One email that our CEO sent to an @msn.com address running on HotMail was delivered to the mailbox 3 times over a period of 6 hours before our MTA saw a successful delivery.

If you use your mailserver at home and you have a dynamic IP then this could be the problem.

Some (many) ISPs don't like to get mail from dynamic IPs. The solution is to use a relay-server, where you send the mail to (main.cf: relayhost=... / transport.cf). Ask your provider if there is a smtp-relay you can use.

I don't use thunderbird, but AFAIK there are settinigs concerning number of concurent connections to the IMAP server. Reduce that number for mail client or set

MAXPERIP=10

in /etc/courier-imap/imapd
Should help...

BTW, I'm using Postfix + courier-imap + maildrop on the gentoo box, works perfectly.
