Subject: DSN problems
Hi all,
I just did a SMTP-GW migration from Sendmail to opensmtpd, now I
have
big problem, the DSN report is really ugly :) and a lot of
users
are
confused if this is a error or what I know that I can
disable...
but
I have to do that in a hundred desktops
The best way I think is do the same as Postfix/Sendmail for DSN, or
better... disable the DSN support.
DSN content structure is a work in progress...
https://github.com/poolpOrg/OpenSMTPD/issues/432
Another problem is a travel system that we use, the system send
emails
with some DSN Flag that opensmtpd is not supported.
Could you provide some more details, which specific flag? logs?
stat=501 5.5.4 Error: Bad NOTIFY parameter syntax
Could you please run...
smtpd -dv -Tsmtp
After run this command I understand better. The main problem is when
opensmtpd receive the message with DSN flag and forward to Postfix, them
postfix reply to the sender and at this time opensmtpd cannot understand
the dsn reply from postfix, so I disable the DSN in Postfix, but is much
better have some way to disable DSN in opensmtpd. I'm still have the
logs.
Any DSN message shouldn't be delivered with DSN flags set and Postfix
does confirm to that behaviour. Without logs we keep guessing.
Anyways, on current OpenSMTPD (git HEAD) you can disable DSN with
no-dsn parameter to listen rule, see smtpd.conf(5).
