How to Fix E: Could not perform immediate configuration on ‘exim4-daemon-light’.

Saturday, March 23rd, 2013

If you get an error like:

E: Could not perform immediate configuration on 'exim4-daemon-light'. Please see man 5 apt.conf under APT::Immediate-Configure for details. (2)

,
During installing Exim with aptitude or apt-get, i.e. # apt-get install exim4-daemon-light

or

# aptitude install exim4-daemon-light

This is due to some kind of mess with other mail server packages (sendmail or postfix) previously installed on the host and some mess with mail servers installed on system, to solve it remove all SMTP server packages sendmail / postfix / exim and then after being sure all SMTP packages are purged from system from clean install Exim light SMTP variant: # apt-get update
# apt-get -f install
# apt-get --purge remove sendmail sendmail-bin
# dpkg --force-all -r postfix
# dpkg --purge exim4-base
# dpkg --purge exim4-config
# dpkg --purge exim4-daemon-light
# apt-get update
# apt-get -f install
# apt-get install exim4-base exim4-config exim4-daemon-light

 

 

Is it possible mail server to work on alternative port to 25?

Thursday, February 28th, 2013

If you're running a small home based Linux or BSD server with Qmail, Exim or Postfix and it happens your ISP has filtered incoming connections to TCP/IP port 25 and you wonder if it is possible to use other alternative port to 25 for example the (Secure SMTP) SMTPS 465 supported by all major SMTP servers, the answer unfortunately is it is not possible.

The only accepted and working mail transmission port works on TCP/IP Port 25, thus the only option to make the mail server working fine is contact your ISP and convince them to remove filtering for port 25 to your custom IP. Many ISPs set a Firewall filter for 25, because nowadays many Windows XP / Vista / 7 PCs get infected with Viruses and Trojans running a tiny SMTP server on the host and trying to send million of SPAM messages via the poor unknowing victim. This congests the network and often even creates ISP network overloads, thus ISPs prefer to filter Port 25 to get rid of such eventual problems.

Once again,  alternative port to 25 for Mail is impossible !

Wine in The Central Park

Friday, January 11th, 2008

I and Alex Drunk Asenovgrad’s Mavrut in the central park it was very cold, but at least an experience. Right now I’m a little hot (cause of the wine). I’m urinating too often recently and it drives me mad. Also I’m a kind of lost I told Sasho about Torsion fields and stuff but he make a fun of that no matter I think that’s a serious matter here is an interview with Nikolay Palushev that may be of an interest to the reader

I hope to meet God soon …
