Hello everybody, I regret that my first post is about a problem but it seems i cannot proceed without your help... The problem is that the mails do not arive into the inbox, from what i can see the plugin dovecot sieve is not suported after the php update and thus thw following error occurs. May 18 18:21:15 digi-web dovecot: deliver(admin@dmydomain): Module is for different version 1.2.16: /usr/lib/dovecot/lda/lib90_sieve_plugin.so May 18 18:21:15 digi-web dovecot: deliver(admin@mydomain): Fatal: Couldn't load required plugins I have installed a perfect server using the Tutorial and i have upgraded into php5.3 using this link http://www.webtatic.com/packages/php53/ The php upgrade was just before i installed ispconfig3 and all went well also the command used was yum upgrade php. also the versions installed were dovecot.x86_64 1:1.2.17-0_115.el5 dovecot-sieve.x86_64 1:0.1.18-6.1.el5 i am currently seaching for a way to fix the problem through google but i do not seem to find something.
