[Bug 1905962] [NEW] local-part of VERP sender may exceed 64 octet

by Yasuhito FUTATSUKI at POEM

Public bug reported: If the recipient mail address is too long, local part of VERP sender may exceed 64 octet, the maximum total length of local-part provided by RFC 5321. I think it should be checked in Mailman/Hander/SMTPDirect.py and fall back to original envsender. e.g. (not tested yet) --- Mailman/Handlers/SMTPDirect.py.org 2018-06-27 17:19:15.000000000 +0900 +++ Mailman/Handlers/SMTPDirect.py 2020-11-27 22:06:44.047857879 +0900 @@ -338,7 +338,14 @@ def verpdeliver(mlist, msg, msgdata, env 'mailbox': rmailbox, 'host' : DOT.join(rdomain), } - envsender = '%s@%s' % ((mm_cfg.VERP_FORMAT % d), DOT.join(bdomain)) + envlocal = (mm_cfg.VERP_FORMAT % d) + if len(envlocal) > 64: + syslog('smtp', + 'local part of VERP address exceeds 64 octet.' + 'fall back to original envsender: %s', + envlocal) + else: + envsender = '%s@%s' % (envlocal, DOT.join(bdomain)) if mlist.personalize == 2: # When fully personalizing, we want the To address to point to the # recipient, not to the mailing list ** Affects: mailman Importance: Undecided Status: New ** Branch linked: lp:mailman/2.1 -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1905962 Title: local-part of VERP sender may exceed 64 octet To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1905962/+subscriptions
