Hello,
I think that I solved issue with timeouts between assp and postfix
(postfix/smtpd)
assp - set IO-Engine from poll to select
assp - set noTLSIP to 127.0.0.1
postfix - disabled tls_random_source
It is wierd but it works.
Dne 06. 08. 21 v 9:24 Thomas Eckardt napsal(a):
your log shows:
Aug-03-21 12:19:30 Worker_3
...
... <--- until here every thing is fine
read from client = EHLO mail-pl1-x647.google.com <--- assp has read
the helo from google
Aug-03-21 12:19:30 server IO::Socket::SSL=GLOB(0x7fde3c853968) poll
(writable) from main sub main::sendque 24 <--- assp has queued the
EHLO in the outqueue to your MTA and has set the writeable FLAG to
signal that assp will actively poll the socket (to your MTA) to become
writeable
???? the socket to your MTA does not signal, that it can write
Aug-03-21 12:22:42 client Timeout after 180 secs <--- google is
waiting for the "250 OK" , assp is waiting for the socket to become
writeable ---> assp detects the timeout
I would monitor the actions at your MTA for such a connection.
If this will not show anything, I would try:
- switch the assp IO-Engine from 'poll' to 'select'
- disable SSL to your MTA (use plain sockets) - assp will not use
STARTTLS

Updated all the above, except the two that were current already
IO::Poll 1.46
IO::Select 1.46
IO::Socket::INET6 2.72
IO::Socket::SSL 2.071
Net::SSLeay 1.90
OpenSSL 1.1.1k 1.1.1k
No change, still suck at
read from client = EHLO mail-pl1-x647.google.com
client Timeout after 180 secs
client was readable
client was not writable
Per above logs. Increasing debugging on SSL and setting ConTimeoutDebug
did not provide any further output.
I also tested Qmail directly and TLS works fine there, so something is
amiss with ASSP. I am at a loss, but still looking.
No [TLS-in] [TLS-out] works, only [SSL-in] [TLS-out].
