it doesn't seem to be fatal, but the line "THIS IS A BUG IN THE CALLING SOFTWARE" made me want to report it.

Do you have a way to reproduce this bug (I am unable to reproduce it)?

 

[IEM]

i don't think so.

but then, i'm not sure how to reproduce "host-based checks during SMTP" anyhow.
hints?

 

[dietmar]

Yes, thats indeed difficult. But the above logs contains "localuser\@example.com", so I thought you produced that by
sending some kind of test mail?

 

[IEM]

nah. that was just anonymising the original addresses.

 

[dietmar]

nah. that was just anonymising the original addresses.

Well, that explains why I can't reproduce anything (what a waste of time, sigh!).

 

[IEM]

sorry to have wasted your time, but, I figured that:
- `example.com` addresses would obviously be fake addresses
- I was reporting a *real* issue I was seeing in my production system (with read addresses; which rules out the `example.com` addresses)
- posting non-anonymous email data on a public forum (dealing with spam-protection!!!) would be considered a big NO-GO for the entire community.

 

[IEM]

btw, I can also provide the real log-files if you are interested. just not on a public forum.

Yes. Please send to dietmar at proxmox.com
