HELO pattern flag
some things noticed after installing 2.99.56pre4:
I used to (back when I still was using 2.99.50s1, i.e., yesterday)
just used flags "ve". However, the newer proto-smtpserver.conf
files say that "ftve" set requires enable-router, so I left just
the flag "R" in there.
1. However, running smtpserver with flag "R" causes errors-on-error
conditions to generate an error mail to postmaster (this condition
does not seem to happen without the "R" flag).
Stranger still, the error mail that is generate says the following:
Your message is being returned unprocessed.
The following annotated envelope headers illustrate the error(s):
Error in "to" envelope address:
Error in "To" header address:
It is like, ZMailer will forget what the RFC says if the "R" flag
is present; "expected word" inside a null return path is not what
I would expect from ZMailer.
2. If I replace the "R" flag back with "ve", the bounces on the
errors-on-error conditions seem to stop. However, I have not
re-enabled the interactive routing subsystem. This looks strange
based on what proto/smtpserver.conf says.
3. I checked my old (abandoned 2.99.53) config files, and found that
I was using "." for an empty set of HELO flags. This seems to still
work with 2.99.56pre4, but seems undocumented (at least in proto/
smtpserver.conf). Actually, all the HELO flags seem to be undocumented
IIRC, I am using new cf files with no local changes.
