takizo, not takezo

Most of the outgoing SMTP server allowed the user to set different sender email address once it is authenticated. But we might be in risk for allowing the user to send outgoing bulk/spam email via authenticated SMTP with different sender email address.

In Exim mail MTA, it can restricts at the SMTP authenticated transport.

accept  authenticated = *
          sender_domains = < the_domain_name_1 > : < the_domain_name_2 >
          control       = submission
          control       = dkim_disable_verify

Usually local_domains is the list of the domain hosted on Exim mail server, it can be configured as below too.

accept  authenticated = *
          sender_domains = +local_domains
          control       = submission
          control       = dkim_disable_verify

there are over thousand emails queue in our mail server, even though I have configured email frozen more than 10 days automatically delete/remove, but it seem like doesn’t work as expected.

here is the work around if you plan to do it manually.

start with listing email queue in the server, by using the command exim -bp, it will list all the email currently queue in the server. but my only concern is frozen email in the server, which I would like to manually clean it from the queue. let try something here,

exim -bp | grep frozen

18d 24K 1JhiI4-00096B-OW <> *** frozen ***
18d 2.3K 1JhiII-00097Y-8s <> *** frozen ***
16d 2.8K 1JhiKM-0009AL-9M <> *** frozen ***
15d 2.3K 1JhiLO-0009Bs-EF <> *** frozen ***
15d 2.5K 1JhiLS-0009Bx-O2 <> *** frozen ***
12d 2.7K 1JhiNm-0009S5-AQ <> *** frozen ***
10d 3.3K 1JhiPv-0009aN-Vu <> *** frozen ***
10d 24K 1JhiQ9-0009as-4R <> *** frozen ***

There are the emails currently queue in the server, and now you might want to check why did the email was queue in the server by exim -Mvl

2008-04-02 15:58:52 Received from <> H=(xxx.xxx.net) [202.76.234.132] P=esmtp S=2143 id=20080402075613.8287E22E8BB@xxx.xxx.net
2008-04-02 15:58:52 routing failed for rsvundet_2002@xxxx.com.my: User account not exist
*** Frozen (delivery error message)

If you want to remove all the email from queue more than 18 days, try this command;

exim -bp | grep 18d | awk ‘{ print $3 }’ | xargs exim -Mrm
