Hello colleagues!
Please help me solve the problem with duplicate letters when sending mail. The
problem manifests itself in one of two cases, and the solutions are mutually
exclusive:
We have a mailbox emar...@domain.com, to which some external analytics
application has access. This mailbox is published on our website. Letters
coming to this mailbox should be sent to some of our managers. To do this, I
use one of two solutions:
a) using the virtual_alias_maps mechanism, I add a line like this to the
"virtual" file:
emar...@domain.com
emar...@domain.com,manag...@domain.com,manag...@domain.com,manag...@domain.com
b) using the virtual_alias_maps and recipient_bcc_maps mechanisms, I add a line
like this to the "recipient_bcc" file:
emar...@domain.com emarket-manag...@domain.com
and add a line like this to the "virtual" file:
emarket-manag...@domain.com
manag...@domain.com,manag...@domain.com,manag...@domain.com
In both cases, each email addressed to emar...@domain.com comes twice. The
problem is solved by adding the option "-o receive_override_options =
no_address_mappings" to master.cf, but then the problem arises in the case #2:
We have two mailboxes that belong to retired employees. Their letters need to
be forwarded to the remaining employee. To do this, I use one of two solutions:
a) using the virtual_alias_maps mechanism, I add the following lines to the
"virtual" file:
retir...@domain.com remaining-mana...@domain.com
retir...@domain.com remaining-mana...@domain.com
b) using the recipient_bcc_maps mechanism, I add the same lines to the
"recipient_bcc" file:
retir...@domain.com remaining-mana...@domain.com
retir...@domain.com remaining-mana...@domain.com
In both cases, there is the following problem: if the sender indicated both
recipients in the letter (retir...@domain.com and retir...@domain.com), then
the manager will receive the letter in duplicate. Removing the "-o
receive_override_options = no_address_mappings" option from master.cf solves
the problem, but then the problem arises in case # 1.
Is there a way to solve both problems?
My Postfix version is 3.4.9, it works in conjunction with dovecot. Postfix does
not receive mail directly: letters first go to our mail provider, and then
Fetchmail takes them from there and sends them to employees.
Here is the content of my "master.cf" file:
