You should use a process limit matching the number of amavisd

Have a look how smtp-amavis is setup in master.cf, if there is no
limit set the default (100) applies. This *could* be your problem.
Thank you,
Here is what I have in my master.cf:
127.0.0.1:10025 inet n - n - - smtpd
-o content_filter=
-o local_recipient_maps=
-o relay_recipient_maps=
-o smtpd_restriction_classes=
-o smtpd_delay_reject=no
-o smtpd_client_restrictions=permit_mynetworks,reject
-o smtpd_helo_restrictions=
-o smtpd_sender_restrictions=
-o smtpd_recipient_restrictions=permit_mynetworks,reject
-o smtpd_data_restrictions=reject_unauth_pipelining
-o smtpd_end_of_data_restrictions=
-o mynetworks=127.0.0.0/8
-o smtpd_error_sleep_time=0
-o smtpd_soft_error_limit=1001
-o smtpd_hard_error_limit=1000
-o smtpd_client_connection_count_limit=0
-o smtpd_client_connection_rate_limit=0
-o
receive_override_options=no_header_body_checks,no_unknown_recipient_checks
Also, in /etc/amavisd.conf:
$max_servers = 2;
...and I only see two amavisd processes (as expected); but these two
take 49,9% of the CPU each.
So, any advice would be welcome.
One critical question, now, is whether I can stop/restart postfix/server
without risking losing deferred mail messages!
Thanks,
Nick
