Postfix rejects emails to addresses in MAIL FROM/RCPT TO that start with "-", for example:
In log we have "warning: Illegal address syntax from ..... in RCPT command".
As I understand, it's not RFC-compliant. I didn't read RFCs carefully. But here is short description in Wikipedia - http://en.wikipedia.org/wiki/Email_address#Local_part
As example, one of the biggest Russian free email service provider (mail.ru) permits such emails.
Can I tune this behavior without changing code?
What reason to place too tight restrictions on email address syntax (especially on the local part)?
Thanks in advance and thanks for Postfix!
