Hello,
I'm working on a map for restrict MAIL_FROM declared on mail based on
sasl user authenticated.
For example if we want that all accounts for domain @domain1.com can
define MAIL_FROM @domain1.com and @domain2.com accounts:
@domain1.com accou...@domain1.com accou...@domain2.com
accou...@domain2.com accou...@domain2.com
@domain2.com accou...@domain1.com accou...@domain2.com
accou...@domain2.com accou...@domain2.com
I store this on map file and add this configuration on postfix:
smtpd_sender_login_maps: hash:/etc/postfix/sender_restrictions_map
smtpd_sender_restrictions
.....*
reject_sender_login_mismatch*
This seems works fine, but is incremental complexity of this map when we
add several domains and this domain has several accounts, for example if
we add 4 domains with 20, 30 o 50 accounts each one.
There are any way to do something like this:
@domain1.com @domain1.com,@domain2.com,@domain3.com
@domain2.com @domain1.com,@domain2.com,@domain3.com
@domain3.com @domain1.com,@domain2.com,@domain3.com
The final purpose is restrict domains can be used on MAIL_FROM, based on
domain used on SASL account. Without consider each account.
Thanks!
