The mailing list for listmasters using Sympa

[Steve Shipway <address@concealed>]

We have a situation on our Sympa server where the outgoing queue in /var/spool/sympa/outgoing appears to be taking a very long time to drain.

 

Although the incoming queue in /var/spool/sympa/msg  rarely even gets above 10 and never gets over 20, the outgoing queue can hit  500 or more before slowly draining at about 200 msg/hr.  The SMTP queue on the host in question never goes over 1 and the mail smarthost has stacks of capacity (we have Nagios and MRTG monitoring of the queue lengths – let me know if anyone wants the relevant plugins to achieve this)

 

In sympa.conf, we have maxsmtp=200 , nrcpt=50 and avg=10.  Most email addresses will be in one of two domains.

 

Does anyone have an idea why the outgoing queue might take so long to clear?  I would have thought it could drain faster that this – and that if anything messages would end up in the sendmail queue.  Do we have something misconfigured?  Is there something that might be locking the outbound queue?

 

Any help appreciated,

 

Steve
