Hi For test I create aliasgroup ~100 user. For test i try send like: for i in {1..10}; do echo "asdasdasdasda" |mail aliasgr...@domain.ltd;done & (for test x 4) - I known this is stupid
In log i found "Connection timed out" and I dont known what value exceeds 10.0.100.5 - this is dovecot with lmtp to deliver main.cf: .... virtual_transport = lmtp:inet:10.0.100.5:24 lmtp_destination_concurrency_limit = 100 - > probably this is value - but I may be wrong - maby check this value to 600 ? default_destination_concurrency_limit = 100 lmtp_destination_recipient_limit = 1 ..... master.cf: .... smtp inet n - y - 100 smtpd -o receive_override_options=no_address_mappings .... In log I found: Nov 3 10:42:07 thebe4 postfix/lmtp[29734]: 4CQPvC3gPyz20nRG: to=<user....@domain.ltd>, orig_to=<aliasgr...@domain.ltd>, relay=none, delay=7.7, delays=0.25/0.28/7.1/0, dsn=4.4.1, status=deferred (connect to 10.0.100.5[10.0.100.5]:24: Connection timed out) I have other question How I tune conf if in aliasgroup user set 1000 address in aliasgroup and send 1 e-mail ? --
