Hi all,
I have a strange problem on my Profix installed on a Ubuntu live web server.We are using postfix for sending & receiving mails. For a perticular virtual server if I change or deleted an existing Alias, it will stops sending & receiving emails for the whole server. I have attached the error when I get on those occations.
So to get into normal mail operation I have to delete the whole Alias & re-create it again as a fresh one.
For an example
info@mydomain.co.uk has an alias > name1@ctc-solutions.co.uk
If I add another one
info@mydomain.co.uk has an alias > name1@ctc-solutions.co.uk, name2@mydomain.co.uk
Its working fine. But if you edit a existing alias like
info@mydomain.co.uk has an alias > name1@ctc-solutions.co.uk, name2222@mydomain.co.uk
it will stop all mail sending & receiving
If you delete/change or etc.. name2222@mydomain.co.uk or the other one, but still mail not working.
If I delete the whole record & re create that, then it starts wroking.

Thanks
Milindra

This looks like the key.

64.18.7.10 does not like recipient.
Remote host said: 554 <milindra.senaratne@ctc-solutions.co.uk>: Relay access denied
Giving up on 64.18.7.10

What is that IP?

The IP is not really familier. According to my knowledge we dont have that kind of IP. Any way to track or find about that?
thanks

Can you post "postconf -n" and a couple of offending alias lines (copy and pasted)

Sorry waht does mean that couple of offending alias lines?
thanks

Why do you have virtual alias maps defined? Are you postmapping the alias file when you change it?
I meant to post lines from you alias file that cause the problem (not a re-type)

Hi Im not a expert on Linux. Postfix was installed by someone else. Im adding the Aliases through webmin grapgical interface.
But if you can tell me which file you need to see, I can post that file for you.
Thanks

Don't bother then, but what about the rest of the questions?

The thing is if I change or delete an existing Alias it will stop sending/reveiving emails.

Hi,
I still have this problem but found out the following.
If I edit or delete existing alias that will stop receive email(problem before).
Lets say I edited one (so it will stop recv emails).Then if I create a new alias (different one for any domain) that will starts work again as usual.
Does this make sence?
So it looks what ever happen when i edit/delete as alias automatically solve if I create another new one.
Can any expert say what is the connection on above 02 process?

Thanks
