Postfix SMTP problem :(

billymayday · 03-11-2008, 03:45 AM

Note that I can't reply to your email because the reply to address is @localhost...

hmm weird. coz ive been testing it with my companies email account too and I can never recieve emails from my server unless i REPLY to it.

djgc · 03-11-2008, 03:50 AM

ok i tried it with my friends GMAIL account and he actually recieved the email!!!..

soo hmmm wut could be the reason for my office account and hotmail not recieving? coz id love to be able to send to hotmail users too since a lot of friends and ppl use hotmail.

ya i noticed that too the address is localhost.domain.
do u know where i change that?

As I said earlier (I think), myorigin, but it could be a squirrelmail setting too

djgc · 03-11-2008, 03:58 AM

ah. coz ive never touched squirrel setting. all i did was yum install it and it did everything. hahaa. coz i was reading this website on how to setup mail server and it never said anything about configuring squirrel. it was mainly configuring dovecot and postfix.

Then change your myorigin setting in main.cf - you set it to hostname rather than mydomain

djgc · 03-11-2008, 04:36 AM

i changed myorigin dont seem to change it either. I tried sending an email to another friends office account and she couldnt recieve my mail as well..
This is weirD~~~ argh.. its like selecting mailboxes to get through hahah..

It is probably reverse DNS as I've said. Where is your domain hosted? You need to set up reverse DNS on your name server.

Basically, a nameserver resolves mail.example.com to IP 1.2.3.4. Reverse DNS checks that 1.2.3.4 resolves to mail.example.com. It's used to catch spam, since most bots will fail this test.

To update your squirrelmail preferences, run

/usr/share/squirrelmail/config/conf.pl

from a terminal.

You can change the sender and reply address when you are logged into squirrelmail using Options - Personal Information. Note this is different from the 3 lines above

djgc · 03-11-2008, 04:56 AM

yes i managed to change it ! and it works. but still some ppl cant recieve emails .. only selective email accounts can it seems.. weird tho. >.<

billymayday · 03-11-2008, 04:57 AM

What distro are you using - I suspect your hostname isn't set up properly

type hostname and hostname -d in a terminal

djgc · 03-11-2008, 05:04 AM

ya its tripped out because if i use REPLY function in web mail the email would get through but COMPOSE doesnt. so that just bugs me out haha.

i tried those 2 commands u listed and this is what showed up.

[root@mail squirrelmail]# hostname
mail.siubeen.com
[root@mail squirrelmail]# hostname -d
siubeen.com

Well that looks OK

Sort out the DNS issue and hopefully you'll be fine.

The other way around it is to relay through your ISP with the relayhost option in main.cf (unless it's a dodgy ISP). What happened when you tried it earlier?

djgc · 03-11-2008, 05:10 AM

what DNS issue do i have that you're talking about?

i actually tried relayhost = [myisp_hostname]

but it got denied hahaha =p

Actually, a more likely cause is your clock. The email you sent me are dated 9 hours ahead of me, which isn't a valid timezone. These are probably filtered out by spam filters and the like.

On revers DNS, I gave a short version earlier, but do a search for a longer version.

Your ISP's server is probably called something like mail.your.isp or smtp.your.isp. I'm pretty sure you don't want the square brackets around it.
