Dear all ,
We had setup a Plesk 10.0.1 control panel , running on a CentOS 5.5 64bit . We are facing a problem with webmail (horde) . When trying to send an e-mail from webmail , nothing is sent (horde claims that message was sent successfully).
We are using qmail as mailer-daemon . Here are some tests I 've made :
1) Tailing /usr/local/psa/var/log/maillog (and grep through using the recipient's address gives nothing) .
2) /var/log/psa-horde/psa-horde.log gives no useful info on this subject , only some login errors ...
3) I tried using tcpdump on lo (I believe horde connects to loopback to send mail) but nothing appears .
4) Manually connecting to lo using telnet and sending mail (worked ok)
5) I saw another post on this forum , mentioning something about changing the symbolic link of sendmail binary . Although in our case sendmail bin links to /etc/alternatives/mta which also links to /var/qmail/bin/sendmail (i believe that's correct) , I tried the solution described there without any luck ...
We have also applied some firewall rules that only permit root , qmail and mailman user to connect to port 25 for outbound traffic . These rules do not apply on lo though (tested using telnet and a local user) .
I am running out of ideas so please in case someone figures out something that could be causing this problem feel free to share it
Thank you in advance ...
