Hi, list
My log is getting quite a few of
Failed to retrieve helo string
immediately followed by
Disabling route
interestingly, I don't see the same behaviour on another smtpd host I
have... now I am even more puzzled
started to think that this had to be something with my local setup, and
thanks to Crystal, who suggested running smtpd with -d and -T transfer,
I went furhter and did a run with -T all, which revealed that smtpd
could not retrieve helo string from a helo-src table, where I had spaces
around the equal sign...
so it was not helo string from remote server, but helo string from
helo-src table.
now spaces around = are removed, and I think "helo string" errors are
gone. let's see!
they are not... but apparently IPv6 addresses need to be put in square
brackets:
lookup: lookup "[2a01:4f9:c010:9411::1]" as ADDRNAME in table
static:helo-names -> "com.krot.org"
warn: failure during helo lookup helo-names:[2a01:4f9:c010:9411::1]
mproc: lka -> dispatcher : 12 IMSG_MTA_LOOKUP_HELO
imsg: dispatcher <- lka: IMSG_MTA_LOOKUP_HELO (len=12)
smtp-out: Error on [2a01:4f9:c010:9411::1] <-> [2a01:4f9:c010:9411::1]
(com.krot.org): Failed to retrieve helo string
feeling silly now -- sorry for all the noise!
gonna dig later... will report when/if I figure this out
