 New Comment:

The sames happens when using mail() with the 'From' part of the extra
headers.

php uses this Header From part (and others for RPath etc..) for the
"MAIL FROM" address in the SMTP protocol, at least if you didn't
specify the sendmail_from setting in php.ini.
But for one reason or another, php (I thínk it's php) wraps this part
in "<" and ">" again!

The workaround is not to use the special format -User <xxx@yy.zzz>-,
but just the e-mail address "xxx@yyy.zzz".  Of course then php
scripters who like a professional approach and want to use this special
format, ..well..they can't, at least not per php script.


I use a Domino SMTP server on Win32.
P.S. I saw several bugs of the same kind allover.  Some are even
wrongly closed, I presume.

can we at least just implement stripping of leading and trailing white
space on what is extracted from the headers? (as that'll fix 35013).

See also bug #35013, one more way how headers are parsed wrong.

See also bug #32600 (rpath set wrong too)

The above patch is wrong. Only acceptable form for RCPT TO:
is:

RCPT TO:<mailbox@example.com> 

Notice the brackets. Do not confuse yourself with RFC2822..
It does not obsolete 2821 as it talks about different thing.

So the fix is to drop the outside brackets stuff out of the addresses.

Here's a possible patch for it. It's pretty simplistic, bit it should
work:

NOTE: I haven't actually *tested* this, it may not even compile. If it
doesn't, please send me a note and I'll try to fix it.
