[Slackbuilds-users] MTA used by submission form doesn't use FQDN in HELO

[Sebastian Arcus]

The submission form at SBo does a check on the email address to the 
originating MTA when a package is uploaded. However, the MTA used by the 
submission form uses just "slackbuilds.org" as HELO name. I know the RFC 
only recommends, not requires, a FQDN for smtp HELO names, but the vast 
majority of reputable SMTP servers use an FQDN nowadays. So much so 
that, as an email server admin, you are pretty safe rejecting 
connections presenting any other type of HELO, as they are 99.9% spam 
from trojan bots.

I just tried to upload a package update at SBo, and had my email address 
rejected, as my own email server, in turn, rejected the connection 
attempt from SBo. I temporarily disabled the relevant check in my 
config, but would it be possible to reconfigure the MTA at SBo's end at 
some point, to present a FQDN, not just "slackbuilds.org"? The mailing 
list comes from a different MTA, I presume, as it presents a proper 
HELO. Only a suggestion.
