This seems like a common problem judging from the "me too"s I got.
Full marks (and a big thank-you) goes to Sverre Slotte Jr. for
pointing out the problem. The problem was that my mail messages did
not end with a new line character, this was because I had changed my
signature file and did not have a NL on the end of the last line.
This is a problem because the sendmail protocol demands a . on a line
by itself to indicate the end of the mail body, what was happening in
my case was sendmail was transmitting the message but because there
was no trailing NL the receiving sendmail did not see a dot on a line
by itself so it thought there was more message to come and would wait
until it eventually timed out.
So anyone that had this problem should check carefully that their mail
messages end with a trailing newline. If you use emacs you should
check the variable require-final-newline is set true to ensure emacs
adds a trailing newline if one does not exist.
