[SOLVED] dovecot/postfix setup issues

GrahamVH · 11-19-2014, 08:24 PM

Howdy,
I'm attempting to build a local network email server for my personal network. What I need from it is a pop3 interface which I can access via my workstation, and a SMTP interface for it to recieve mail.

I am currently attempting to use dovecot and postfix to accomplish this. Currently dovecot is working (as far as I can tell, my mail client can log in and get mail, and it isn't spewing any Errors to syslog).

postfix's ability to get mail to dovecot, however, isn't working...
Any attempt I make to send mail to an account on the system results in the error:

Code:

send-mail: RCPT TO:<#####@#####> (451 4.3.0 <#####@#####>: Temporary lookup failure)

syslog slows the following:

Code:

Nov 19 19:16:10 ### postfix/smtpd[12940]: warning: hash:/etc/aliases is unavailable. open database /etc/aliases.db: Invalid argument
Nov 19 19:16:10 ### postfix/smtpd[12940]: warning: hash:/etc/aliases lookup error for "##@###.localdomain"
Nov 19 19:16:10 ### postfix/smtpd[12940]: NOQUEUE: reject: RCPT from ###.localdomain[#.1]: 451 4.3.0 <##@###.localdomain>: Temporary lookup failure; from=<root@###.localdomain> to=<##@###.localdomain> proto=ESMTP helo=<###.localdomain>

I have been fiddling with the aliases for a bit any not been getting anywhere. However, running newaliases does nothing.

This setup is on a Fedora 20 system.

Any help would be appreciated.

Make sure that /etc/aliases exists. If not create it with

touch /etc/aliases
newaliases

Also make sure you have

alias_maps = hash:/etc/aliases

in the /etc/postfx/main.cf

The /etc/aliases file exists, and the newaliases command just tells me 'newaliases: In sSMTP aliases are read from a plain text file'
The /etc/postfix/main.cf file also contains the 'alias_maps = hash:/etc/aliases' line uncommented.

So unfortunately that is not the issue.

Is that the only error in the /var/log/maillog?

send-mail: RCPT TO:<#####@#####> (451 4.3.0 <#####@#####>: Temporary lookup failure)

Take a look at the timestamps and put all the errors in that timeframe here.

Are you using MySQL for your Postfix users?

Problem Solved.
I poked around with the aliases a bit more and found that /etc/aliases.db was an empty file. Through some googling I found that my alternatives for mta was set to /usr/sbin/sendmail.ssmtp instead of /usr/sbin/sendmail.postfix.

Once I changed the alternatives, everything worked fine.

Thanks for the help.

run the command 'alternatives --config mta' and choose the postfix option
