Does the canonical_maps rewriting apply before the restrictions in smtpd_relay_restrictions?

[deoren]

Hi,

I'm likely overlooking this (I'm still digging), but do the restrictions 
in smtpd_relay_restrictions apply before the rewriting configured for 
canonical_maps takes place?

I'm trying to rewrite the sender address for a system before its mail is 
relayed and it appears that the reject_non_fqdn_sender restriction is 
applying before the rewrite can be completed. I assume I'm just doing 
something wrong, but wanted to double-check on the timing/ordering 
before I continued to troubleshoot much further.

Thanks in advance for your help!
