[sendmail] virtusertable not being used or not working


Hello all

I've had a problem with virtual email addresses on one of my servers. Basically, the email address enquire@asureimage.com translates to the account enquireasi (which is /sbin/nologin).

I can send email from enquire@asureimage.com, but not receive email to it. I can, however, receive email to enquireasi@asureimage.com. This suggests virtusertable isn't being read or used.

Everything was fine until I added a new email address to virtusertable this morning, ran it through m4, and restarted sendmail.

I haven't upgraded sendmail, or made any other changes to the configuration. I only restarted it because of the change to virtusertable.

Here is a copy of virtusertable: Removed

Here is a copy of sendmail.mc: Removed

Here is the reference to virtusertable in sendmail.mc...
FEATURE(`virtusertable', `hash -o /etc/mail/virtusertable.db')dnl

This is the correct address, as evidenced by entering this at the command prompt: ll /etc/mail/virtusertable.db

I restored the old virtusertable, and the problem didn't go away. After much searching, trial and error, I'm at a loss to know why I'm getting mail bounce back with this message:
=====================================================
SMTP error from remote mail server after RCPT TO:<enquire@asureimage.com>:

What is the output of:
Code:
sendmail -bv enquire@asureimage.com
sendmail -bv enquireasi@asureimage.com
To rebuild the virtusertable database you can run:
Code:
makemap hash /etc/mail/virtusertable.db < /etc/mail/virtusertable

Hi Bathory

Thanks for your help

Here's the salient part...

I'd been using m4 to rebuild virtusertable.db, as I'm...
  • Used to using it to rebuild other .db files
  • An idiot
I figured there was no point trying the 'make' solution, but then realised the problem is definitely in virtusertable.db (only thing that's changed), and that I have a history of foolishly disregarding this type of advice from experts

Naturally, your solution worked immediately and my virtual email addresses are being directed to the underlying accounts.

Thank you very much.

Regards
Wayne
