some problems that i faced when setting up a mail server

Hi all,

While setting up a mail server, i had faced some problem while trying to make it run properly.

Hope if u encounter such errors, this thing might help u all.

All the errors started , when i installed amavis and configured it.

Error 1

file master.cf

amavis unix – - – - 2 smtp
-o smtp_data_done_timeout=1200

Error message in the log file:

bad transport type: smtp_data_done_timeout=1200

Solution: note that you need leading whitespace before the -o directives.

so do not forget to give a white space.

Error 2

When starting amavis , you may get this error.

/etc/init.d/amavis start
Starting amavisd: The value of variable $myhostname is “aganith”, but should have been a fully qualified domain name; perhaps uname(3) did not provide such.
You must explicitly assign a FQDN of this host to variable $myhostname
in amavisd.conf, or fix what uname(3) provides as a host’s network name!
(failed).

Solution: Just include $myhostname=’mail.yourdomain.com’; in the 50-user file within the amavis directory. Remember to include a FQDN.

Note: I am using ubuntu as my server OS. Dono where to add this line in RedHat based versions.

Error 3:

connect to 127.0.0.1[127.0.0.1]: Connection refused (port 10024)

and

TROUBLE in pre_loop_hook: db_home directory is not writable: /var/lib/amavis/db at /usr/sbin/amavisd-new line 6451

Solution:

For this , i just changed the permission for the db directory

chown -R virtual:virtual /var/lib/amavis/db

This command solved both of my problems.

Just restart amavis, clamv(dono if required, i did it) and finally postfix .

and enjoy using the mail server.
