According to the SMTP protocol spec (RFC 5321), SMTP terminates
lines with <CR><LF>, not with newline characters. And it has other
features, such as multi-line replies, and magical handling of lines
beginning with the "." character, that you should be aware of when
before writing SMTP software.

I just tried to replace the "\n" with "\r\l", but to no avail. The same
problem remains.
I also watched the exact reply given by my (working) c++ program, and
that terminates its linex with 0xa, a new line.
Apart from that, you are probably right, I should read the RFC. I hoped
I could soare the hassle, since I am not planning to right something
particular sophisticated.

The php-net-smtp PEAR module implements an SMTP client; you may
be able to pick some pieces to do the server portion of the protocol.

I can be wrong here, but shouldn't that be "\r\n" ?

HTH,

You are right, of course. I had \r\n before, with the same negative
results, and just tried the other variation in desperation.
