Error emailing:The following From address failed:

[rgodoy]

FIXED

See at the bottom.

Suddely my sugarcrm installation (4.2.0 at that time) stopped to send outbound mails.
I've checked a bit but no luck, so I dediced to give a try to the lastest 4.2.1 and upgrade my installation,
outbound email still didn't worked.

So, after more debugging all I got from sugarcrm.log is this:

Fri Jul 14 01:13:06 2006,810 [61045] DEBUG SugarCRM - Email sending ---------------------
Fri Jul 14 01:13:06 2006,996 [61045] FATAL SugarCRM - Error emailing:The following From address failed: email@mydomain.com
Fri Jul 14 01:13:06 2006,999 [61045] DEBUG SugarCRM - -------------------------------> Email called save()

Nothing on my php log, and also nothing on my postfix log.

I've set to use sendmail and localhost SMTP withouth success, also tried with external SMTP with the same problem.

My posfix is configured to allow relay from my localnet and the host on which sugar is installed, I;ve tested local SMTP, by isuing commands on telnet sesion and I've been able to be allowed to relay through, so I scratch my head again and again trying to solve this.

I've patched with the current 4.2.1a and still no luck.

My current setup is:
sugarcrm 4.2.1
lighttpd with fastcgi 4.1.11,
mysql 4.1,
php 4.4,
postfix
FreeBSD

I'm able to deliver email using mail() on a PHP script on this setup. Which discards that the failure is on that side.

If someone can giveme hints about where to look for tracking this on the code, I'll be glad to help out!
I'm quite new to sugar, using it for a couple of months and I have to say this is a great application! good work!
Let me know what information is needed to kill this bug.


Update:
I've also tried what's explained in the following post (changing host.mydomain.com to mydomain.com on config) but no luck still, both with sendmail and localhost SMTP.

I wasn't able to found documentation related specificaly to email delivering on sugar, links/comments would be really appreciated.


FIXED
Well, after lot of trouble I've rethink how I was handling the whole email setup and switched defaults and user/settings to use sendmail. Mails went through with sucess! but still one issue: I use SASL auth for email, and as far I deliver mails from the same machine which hosts the sugar installation I might get rejected due RBL's. So I managed this on the MTA side, not MUA side (as I was trying with sugar settings).

Hope this is useful.
