Unfortunately it seems that Wietse's suggestion was not sufficient for the smtp server. I now get a different (but similar) error: Jun 6 17:14:53 localhostname postfix/smtp[76133]: D7ED9A18A05: to=<user1.h...@work.com>, relay=smtp.work.com[192.168.1.89]:587, delay=1.7, delays=0/0/1.4/0.35, dsn=5.7.1, status=bounced (host smtp.work.com[192.168.1.89] said: 550 5.7.1 Client does not have permissions to send as this sender (in reply to end of DATA command))
The logs were going crazy until I took out the sender_canonical_maps related lines in main.cf and did a postfix reload. I think it kept trying to send. I also need to make sure that the if statement will replace a MAIL FROM sender who is not me rather than not only in my domain. So perhaps it would be?: if !/[[:<:]]user1\.home@work\.com$/ /./ user1\.home@work\.com endif But the mail.log says this is incorrect: Jun 6 17:25:19 gs611-hardradi postfix/cleanup[76238]: warning: pcre map /etc/postfix/sender_canonical, line 1: error in regex at offset 3: unknown POSIX class name Jun 6 17:25:19 gs611-hardradi postfix/cleanup[76238]: warning: pcre map /etc/postfix/sender_canonical, line 3: ignoring ENDIF without matching IF I've tried digging around to better understand the pcre syntax, but I haven't had much luck. I hope I've provided enough info... cheers, mike On Mon, Jun 6, 2011 at 4:22 PM, Wietse Venema <wie...@porcupine.org> wrote: > Wietse Venema: >> Wietse: >> > Why do you believe that it complains about the "From" address in >> > the email header, instead of the SMTP "MAIL FROM" address? >> >> Michael Way: >> > Sorry Wietse, my bad you are correct.
