Hi, When I subscribe the email list in Subscription Policy is confirm, Some problems happen in here： 1.Some mail mua reject send the confirm the message, because the length of recipient is too long. for exmaple: requirements-confirm+9605556e0b35a5da280c1de0d34a3e6f770f8ea5@domain, and the mail mua reject to modify about this.
Well, if the MUA complains, it is the one that is broken. The example is within the specified limits for an address local-part in RFC 5321 (current normative specification for SMTP) section 4.5.3.1.1.
There some message by lookup RFC 5321 and section 4.5.3.1.1 4.5.3.1.1. Local-part The maximum total length of a user name or other local-part is 64 octets.
Some MUAs are very old , and allowed from RFC2821 and not allowed from RFC5321. There is some message in RFC2821: local-part The maximum total length of a user name or other local-part is 64 characters.
