Postfix Postscreen: how to use postscreen for smtp and smtps both
- by petermolnar
I'm trying to get postscreen work. I've followed the man page and it's already running correctly for smtp.
But it I want to use it for smtps as well (adding the same line as smtp in master.cf but with smtps) i receive failure messages in syslog like:
postfix/postscreen[8851]: fatal:
btree:/var/lib/postfix/postscreen_cache: unable to get exclusive lock:
Resource temporarily unavailable
Some say that postscreen can only run once; that's ok. But can I use the same postscreen session for both smtp and smtps? If not, how to enable postscreen for smtps as well?
Any help would be apprecieted!
The parts of the configs:
main.cf
postscreen_access_list = permit_mynetworks,
cidr:/etc/postfix/postscreen_access.cidr
postscreen_dnsbl_threshold = 8
postscreen_dnsbl_sites = dnsbl.ahbl.org*3 dnsbl.njabl.org*3 dnsbl.sorbs.net*3 pbl.spamhaus.org*3 cbl.abuseat.org*3 bl.spamcannibal.org*3 nsbl.inps.de*3 spamrbl.imp.ch*3
postscreen_dnsbl_action = enforce
postscreen_greet_action = enforce
master.cf (full)
