i really need an help to solve this problem:
a customer have an email which generate message from an email we called email@example.com
and i've to divide generated message which starts with + in subject from them doesn't start with. Them with + character have to be sent to another email address as firstname.lastname@example.org
but one copy needs to remain in local; if no + character matches the copy could be simple processed from procmail and amavis.
Have tried with header_checks, but to do this i need a double line if and it is not supported in (check from, check subject content)
Have tryed to redirect message to a new user account in local to process it with .forward and procmailrc commands, but it enters in loop becouse procmailrc receive again the message with same + string in subject and starts again the loading... and so on.
How can i do? There's somethin' already prepared and programmed that can be used for select and redirect some mail on Subject-based content filter?
Thx for help all.
