Hello,
I deliver mails from a Maildir to a dial customer via
serialmail-0.72. The customer is runninc ccMail (don't know which
version), quit yields: "221 ccMail Link to SMTP closing connection".
The problem seems to be that the DATA submission end can't be detected
on the ccMail side (for certain mails):
Router to Mailserver (using NAT):
0410: 64 65 72 20 63 6f 6d 69 63 73 20 6e 65 6e 6e 65 der comics nenne

0430: 41 0d 0a 0d 0a 2e 0d 0a A.......
^^^^^^^^^^^^^^^^^^^ This looks correct. The
transmission should be finished!

Both mails get delivered by qmail & sendmail without problems. I will
try serialmail-0.75 tomorrow, but i wonder if anyone else encountered
this problem ....
