mails from fail2ban dont deliver

[maikcat]

hi there,

i recently installed fail2ban with a couple of jails for zimbra,
it works ok but when it tries to send mail notifications they
appear in mailq but they dont deliver...

also other system notifications dont deliver either

any thoughts?

my system:

centos 5.4 64bit
zimbra 6.0.8 community edition

also
when i run update-alternatives --display mta

it shows

mta - status is manual.
link currently points to /usr/sbin/sendmail.postfix
/usr/sbin/sendmail.postfix - priority 30
slave mta-pam: /etc/pam.d/smtp.postfix
slave mta-mailq: /usr/bin/mailq.postfix
slave mta-newaliases: /usr/bin/newaliases.postfix
slave mta-rmail: /usr/bin/rmail.postfix
slave mta-sendmail: /usr/lib/sendmail.postfix
slave mta-mailqman: /usr/share/man/man1/mailq.postfix.1.gz
slave mta-newaliasesman: /usr/share/man/man1/newaliases.postfix.1.gz
slave mta-aliasesman: /usr/share/man/man5/aliases.postfix.5.gz
slave mta-sendmailman: /usr/share/man/man1/sendmail.postfix.1.gz

slave mta-aliasesman: /usr/share/man/man5/aliases.sendmail.5.gz
slave mta-sendmailman: /usr/share/man/man8/sendmail.sendmail.8.gz
Current `best' version is /usr/sbin/sendmail.sendmail.

thank you in advance
Michael.

Not really as you haven't given any information about the problem. What about starting with the log files to see what the reason is for non-delivery.

[maikcat]

when i give sendmail -v test@mydomain.com < test.txt

the mail appears in mailq and i see nothing related inside /var/log/zimbra.log..

thank you for answering me.
Michael.
