Hi folks,
Looking at my opensmtpd log file (see attachment) some EMails
are greylisted by the peer several times. Apparently the
receiving ISP has several MX hosts, probably each running its
own local whitelist. :-(
Do you think it would be possible in opensmtpd to avoid
hopping from one IP address to another, when the greylisted
EMails are processed again?
opensmtpd is version 6.0.2, running on Debian.
Every helpful comment is highly appreciated
Harri
