:-)Some users forward their incoming mail to some external mail servers. Unfortunately AFAIK with no action taken it may result in breaking the SPF. The solution for this problem I know is rewriting addresses with SRS (postsrsd). Unfortunately postsrsd uses the same settings as canonicals do which in my case is inadvisable because I want canonicals to operate independently of SRS. A few days ago I sent a post regarding this problem.
Unfortunately I haven't received any answer. Using canonicals as well as mail forwarding seem quite common so no answer may suggest that postfix users don't use postsrsd for address rewriting. Moreover I can't find any reference to SRS on the postfix webpage. The conclusion that comes out is postfix provides some other mechanisms for avoiding violating SPF on forward I'm unaware.
OK. I do not insist on postsrsd. I'd really appreciate any suggestion: what can I use instaed of it - what do you recommend?
Best regards, Marek
