Hi,
We have migrated to a new domain yyy.com. We also continue to receive
mails on old domain xxx.com.
When a sender sends a mail to [email protected] (old domain), mail is
received and delivered to user abcd. Abcd when he replies to all (his
from email address will be [email protected] [new domain], and hence, mail
is also sent to [email protected] [old domain]. So, the sent mail is also
received back to the same sender.
When the actual recipient receives the mail, he will have [email protected]
and [email protected] in the address list. So, when he replies to that
mail, 2 mails will be sent to the same user.
What's the best way that, the user receives only one mail, when both
domains are in To addresses?
/etc/postfix/main.cf:
virtual_alias_maps =
hash:/etc/postfix/old-to-new ...other existing maps...
/etc/postfix/old-to-new:
[email protected] [email protected]
# postmap /etc/postfix/old-to-new
# postfix reload
Instead of hash, you can use any supported type.

Sorry for the trouble. But, after doing that, when I sent a mail from
outside to both these email addresses [email protected] and
[email protected] (in a single mail) , 2 emails came instead of one. I
want that, if both these domains are listed in the same mail, only one
mail should be received.
Hope this clarifies my requirement.

IMPORTANT NOTE:
ISRO Satellite Centre (ISAC) was renamed as U R Rao Satellite Centre (URSC).
Hence, the existing domain (isac.gov.in) is changed to new domain ursc.gov.in
resulting into change of e-mail address from [email protected] to
[email protected].
Please note this change and update your contact details for new domain
(ursc.gov.in).
