Submission / Postfix / XCLIENT

Hi all,

while testing the new Dovecot Submission Proxy feature, which we greatly appreciate and have been anticipating for a long time, some issues occured.

Dovecot is unable to submit mails via XCLIENT:

< XCLIENT ADDR=185.115.176.12PORT=39074

501 5.5.4 Bad ADDR syntax: 185.115.176.12PORT=39074

Postfix is unable to parse the XCLIENT command from Dovecot submission proxy, as a space seems to be missing.

After checking the source code, the issue looks easy to fix - at least to me as a non-Developer.

I created my first pull request for that:

https://github.com/dovecot/core/pull/90

Would be great to see this merged.

Any additional comments are also appreciated.

Best, Anton
