Subject: Setting up virtual alias domains and maps - failing to deliver
To: postfix-users@postfix.org
Following recommendation from Viktor, trying to set up virtual alias domains.
Previous arrangement works fine: domains in mydestination, local
transport uses lmtp to cyrus. Here is an example of that arrangement
- sent off to Amavis, then off to lmtp for successful delivery:
Mar 23 14:25:35 emp87 postfix/lmtp[327725]: E85581819E5:
to=<ka...@simonandkate.net>, relay=127.0.0.1[127.0.0.1]:10024,
delay=6.9, delays=2.3/0/0/4.6, dsn=2.0.0, status=sent (250 2.0.0
from MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as 752C71819E6)
Mar 23 14:25:35 emp87 postfix/lmtp[327851]: 752C71819E6:
to=<ka...@simonandkate.net>,
relay=mail.simonandkate.net[/run/cyrus/socket/lmtp], delay=0.23,
delays=0.01/0/0/0.22, dsn=2.1.5, status=sent (250 2.1.5 Ok
SESSIONID=<cyrus-327579-1616473535-1-15937860855307597156>)
Changes:
mydestination - removed, left as default
virtual_alias_domains = simonandkate.lan, simonandkate.net, etc...
virtual_alias_maps = hash:/etc/postfix/virtual (and postmapped)
Removed all virtual alias domain entries from aliases and run newaliases
The domain alias appears valid:
[root@emp87 postfix]# postmap -q ka...@simonandkate.net
hash:/etc/postfix/virtual
katie
Save changes, postfix reload
Mar 23 14:46:48 emp87 postfix/lmtp[329453]: ED7531819E6:
to=<ka...@simonandkate.net>, relay=127.0.0.1[127.0.0.1]:10024,
delay=11, delays=2.4/0/0/8.6, dsn=2.0.0, status=sent (250 2.0.0 from
MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as 371701819EA)
Mar 23 14:46:48 emp87 postfix/error[329457]: 371701819EA:
to=<ka...@simonandkate.net>, relay=none, delay=0.02,
delays=0.01/0/0/0.01, dsn=5.1.1, status=bounced (User unknown in
virtual alias table)
So it initially accepts the email, sends to amavis, gets it back,
and then fails to deliver, bouncing with 'relay=none' and 'User
unknown in virtual alias table'.
How do I get that second step to deliver to lmtp?? I'm obviously
doing something fundamentally wrong with the setup, but I can't pick
it... so I have reverted back to using domains in mydestination for
now...
Simon
I've scaled back, taking on board Noel's suggestion of just using
virtual_alias_maps for the exceptions I need to rewrite, but *not*
moving any of the hosted domains from mydestination to
virtual_alias_domains.
That achieves what I need and works as expected.
I am still interested to know how to achieve the full
virtual_alias_domains setup if anyone can help on my problems noted
above.
Thanks
Simon
