I'm having a bit of an argument with a customer over the command syntax in RFC 2821 that shows command arguments for MAIL/RCPT commands in brackets, i.e.:

Path = "<" [ A-d-l ":" ] Mailbox ">"
Mailbox = Local-part "@" Domain

Our mail servers reject connections that don't follow the RFC. Am I wrong to do this? This guy certainly thinks so, even after I've cited the RFC and appropriate section, his arguments is "even hotmail does not keep up the standards" and if we ignore them as well. Hotmail at least follows this rule... am I wrong to require the brackets?



No you are not wrong for following the RFC. Customer shouldn't be running broken software that doesn't follow the RFCs.

Point out to customer that AOL requires the brackets as well. and that is probably a better example to use that Hotmail.
