could be a blendmail/smtp thing. there's some option to blendmail (sic)
to double up on leading dots to prevent premature end of the input to
a DATA command. it's also written up in the smtp rfc [rfc821 / std10]:
4.5.2. TRANSPARENCY
Without some provision for data transparency the character
sequence "<CRLF>.<CRLF>" ends the mail text and cannot be sent
by the user. In general, users are not aware of such
"forbidden" sequences. To allow all user composed text to be
transmitted transparently the following procedures are used.
1. Before sending a line of mail text the sender-SMTP checks
the first character of the line. If it is a period, one
additional period is inserted at the beginning of the line.
2. When a line of mail text is received by the receiver-SMTP
it checks the line. If the line is composed of a single
period it is the end of mail. If the first character is a
period and there are other characters on the line, the first
character is deleted.
sounds like a bug. why am i not suprised?
it may also be an issue with nntp.
