Hello All, Our team successfuly used James mail server for a project untile we've got a requirement to support sub-addressing. It turned out that James does not support a tag appended to the local part of email address (ex: [email protected]). RFC 5233, refers to this convention as sub-addressing, but it is also known as plus addressing or tagged addressing. To resolve this issue our team have developed 'SubAddressingValidRcptHandler' which extends from 'org.apache.james.smtpserver.fastfail.ValidRcptHandler' class. Also to find the right addressee by email address with sub-addressing we have developed matcher 'SubAddressingMatcher'.
I do not know if you have plans to implement the sub-addressing support. I can send you our code for review and will be happy if our changes save time for other developers who faced with the same issue as we had. Please let me know if that makes sense and which way I can send the code for review. Thank you, Sergey Lysenkov
