Ah. That makes sense; because I am using virtual users, I guess postfix doesn't 
know when to stop.
I added in:

user1firstname.lastn...@domain1.com user1firstname.lastn...@domain1.com
user2firstname.lastn...@domain1.com user2firstname.lastn...@domain1.com

which are the actual end results and that catches that final rewrite. I realise 
the first one isn't strictly necessary given the catchall; but just for 
consistency!

Thanks - that was a great help.

Cheers,
David

You presumably have the default setting:
append_at_myorigin = yes

Refer to http://www.postfix.org/virtual.5.html. Bear in mind that
processing of virtual alias table is recursive.

So: the first time, user2firstn...@domain2.com is rewritten to
user2firstname.lastn...@domain1.com (i.e. the 'myorigin' is appended, I am
guessing domain1.com is set in /etc/mailname)

Because a change occurred this is then passed back through the same file
and (unless you remove the @domain1.com catchall) gets rewritten to
user1firstname.lastn...@domain1.com

Sorry, that got sent prior to my completing the email. I'll try again.

virtual_mailbox_domains = domain1.com, domain2.com, domain3.com

The virtual aliases look like:
user1firstname.lastn...@domain3.com user1firstname.lastname

user2firstn...@domain2.com user2firstname.lastname
user2firstn...@domain1.com user2firstname.lastname
user2firstname.lastn...@domain2.com user2firstname.lastname

@domain3.com user2firstname.lastname
@domain2.com user1firstname.lastname
@domain1.com  user1firstname.lastname


In effect, I have 3 users created for domain1.com. A catchall for domain1 and 
domain2 to direct to user 1. Ignore domain3 for the time being.

For some reason though, all emails are ending up in user1’s Inbox. If I send an 
email from an external email address to user2firstname.lastn...@domain1.com it 
ends up in user1firstname.lastname’s email. If I send an email to 
user2firstn...@domain2.com it also ends up in user1firstname.lastname's email.

Interestingly, if I remove the @domain1.com catchall in the 
/etc/postfix/virtual file, email gets delivered correctly to 
user2firstname.lastn...@domain1.com and user2firstn...@domain2.com.

Postfix logs show (with the catchall):
Jun 16 09:53:18 kopano postfix/smtp[8735]: 9665C6C28C5: to=us...@domain1.com, 
orig_to=us...@domain1.com, relay=127.0.0.1[127.0.0.1]:10024, delay=3.9, 
delays=2.2/0.01/0/1.6, 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 4DFA46C28E1)

Can anyone point me in the correct direction please. I have spent a couple of 
days on this trying to work out where I have gone wrong and I am mystified. 
Happy to provide a more full-featured config if that helps.

Cheers,
David
