postfix can't receive mails but can send mails
 
Hi all,

Server on VM, OS - Ubuntu 1004 server 64bit
Host - Ubuntu 11.04 desktop 64bit
Orcle VirtualBox

I followed;
Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 11.10)
http://www.howtoforge.com/virtual-us...l-ubuntu-11.10

to build this server which will serve multiple domains. It can send mail but unables to receive mail.


$ tail /var/log/mail.log
Code:

create your own dns

deep27ak 02-09-2012 05:09 AM

Postfix is a smtp server and is used to send mails and if you are unable to receive mails configure a dovecot server for pop3 and imap


secondly your DNS is not replying to mail.mydomain so check your DNS.

Whether you meant adding dovecot server for pop3 to receive mails?? Let Postfix to send mails? Thanks

I meant postfix is a smtp server so just configuring your machine with postfix will not help you in receiving mails

configure a dovecot server for the same

SMTP = protocol for SEND/RECEIVE MESSAGES !!

unable to receive mails means miss-config postfix

post here main.config + master.config

@deep27ak dovecot is configured in case you want to enable clients to fetch mails from mail server

@TS it seem your host is not getting resolved when you dig for mail.domain it must reply you with proper answer i.e. it must reply then IP address for your mail.domain it's only then mails can reach your server. make sure DNS is giving reply i.e. ANSWER SECTION when you make a query for host name of your mail server. and as far as your configuration file(/etc/postfix/main.cf) is concern it seems ok to me.
ahh wait it seems you have already fixed DNS part! sorry you may ignore above part.

another thing I've seen that you have enabled "relayhost =" directive I think it is not necessary in case you want your server to accept mails. To the best of my knowledge relayhost is used for forwarding mails to another mail server you might try commenting out that line.

Thank you
regards

Hi,

Thanks for your advice. Tried it.

1) comment out the line "relayhost="
2) restart /etc/postfix

On domain register website

Code:

20                @        smtp.secureserver.net
10                @        ser01.mydomain.com

Whether change
Code:

email        ser01.mydomain.com
to
Code:

email        mail.mydomain.com
OR
Code:

smtp        ser01.mydomain.com
to
Code:

smtp        mail.mydomain.com
can help? But I have to wait for 48hrs for the change to propagate.


Edit:

mysql> SELECT * from transport;
Code:

+-------------+-----------------------+
| domain      | transport            |
+-------------+-----------------------+
| mydomain.com | smtp:mail.mydomain.com |
+-------------+-----------------------+
1 row in set (0.00 sec)

mail.mydomain.com is on "transport" table
