Re: Bug: lmtp proxy does not quote local parts with spaces

There seems to be a bug with RFC822 processing in ltmp proxying that doesn't quote local parts that, for example, contain spaces.

Newer related RFCs are RFC 5321 and 5322.

[ ... ]

MAIL FROM:<test@testdomain.com>\r\n RCPT TO:<deemzed.uk+Junk E-mail>\r\n

501 5.5.4 Invalid.parameters\r\n

That recipient address is totally invalid. It is neither just a local part without a domain, nor a plussed address destination.

Check your setup with i.e.

RCPT TO:<"Junk E-mail"@deemzed.uk>

or

RCPT TO:<"test+Junk E-mail"@deemzed.uk>
