In the meanwhile, I am getting around 200 error messages a day complaining about "cannot fork". I have tried various settings of SMTP_MAX_SESSIONS_PER_CONNECTION and MAX_DELIVERY_THREADS, but that does not seem to help. Does anyone know what the problem could be?
This is not a problem I have had to deal with but I suspect that, as the problem arises when the MTA delivering to MM is trying to spawn a process to perform the delivery, that changing SMTP_MAX_SESSIONS_PER_CONNECTION and MAX_DELIVERY_THREADS will not help much.
These MM config variables are concerned with limiting MM's use of resource when trying to pass outgoing messages to the outbound MTA (which may or may not be the same as the inbound MTA). Only indirectly will they impact on delivery to Mailman by the MTA.
Mailman's delivery function is low cost and concerns itself solely with taking the message from the MTA and getting into the qfiles directory on disc. Once that is done, the heavy lifting of the mail list processing is done by the qrunner daemons.
I suspect you need to provide some idea of what type of machine (CPU, clock rate, memory, disc etc) you are running, what OS and its version, what MTA and such to get some more intelligent feedback from the list than I can provide.

Hi,
since a larger number of lists are hosted on our server, I am running into a problem with the number of processes on the server, which is limited. Is it a way out to set some limit on:
SMTP_MAX_SESSIONS_PER_CONNECTION or MAX_DELIVERY_THREADS
Any other suggestions to keep the number of concurrent processes down, even if delivery takes a bit longer?
Typical errors I get are:
----- The following addresses had permanent fatal errors ----- "|/usr/local/mailman/mail/mailman bounces abc" (reason: 2) (expanded from: <[EMAIL PROTECTED]>)
----- Transcript of session follows ----- Cannot fork: Resource temporarily unavailable 554 5.3.0 unknown mailer error 2
It seems to me that this indicates that the maximum number of allowed processes has been exceeded.
