Correct TO string is not working anymore after upgrade

[dimm0]

Describe the bug

After upgrading to 0.7.1 the correct TO string like To: Name Lastname <[email protected]>\r\n is causing the error:

Was expecting RCPT arg syntax of TO:

Just the [email protected] works.

Steps to reproduce

Send mail to above recipient

Log files

Nothing in logs, but client is getting the error

• maddy version: 0.7.1

go-smtp update included in 0.7.1 removed the "lax" parser for RCPT argument, that might be the reason.

I need a log with I/O to troubleshoot the issue further. Add this to your config:

smtp tcp://0.0.0.0:25 {
  io_debug
  debug
  ...
}

and try again. Look for RCPT line in the log and post it here.

I get something similar..

submission: incoming message {"msg_id":"e0762daa","sender":"[email protected]","src_host":"185217ff75c7","src_ip":"4.5.3.3:33184","username":"[email protected]"}
submission: RCPT ok {"msg_id":"e0762daa","rcpt":"[email protected]"}
submission: DATA error {"addr":"('Test UserFullName', '[email protected]')","modifier":"submission_prepare","msg_id":"e0762daa","reason":"mail: no angle-addr","smtp_code":554,"smtp_enchcode":"5.6.0","smtp_msg":"Invalid address in To"}
submission: aborted {"msg_id":"e0762daa"}

[foxcpp]

submission: DATA error {"addr":"('Test UserFullName', '[[email protected]](mailto:[email protected])')","modifier":"submission_prepare","msg_id":"e0762daa","reason":"mail: no angle-addr","smtp_code":554,"smtp_enchcode":"5.6.0","smtp_msg":"Invalid address in To"}

Looks like you have From: Test UserFullName '[email protected]' in your message whereas the standard syntax is From: Test UserFullName <[email protected]>. maddy enforces additional checks for messages created via submission.

Yah the test is coming from the Authentik server. I'll go investigate there.
