I have a bug with LMTP delivery I think you don't escape correctly the
datas submited to lmtp (and possibly to lmtp to since it seems
to be the
self source portion).
According to rfc2821 (SMTP) Section 4.5.2 (it's formal, but only
for
reference not to annoy you)
I have not yet understood the code but there is an example and
the data
got for each case...
As I understand you do the 2°part (removing starting Dot) but
not the
first.
If i'm able to send you a patch, i'll give it to you Asap.
I think this bug can be annoying as it can cause data loss (i
know a
fullstop si rarely considered "vital" but in 8 Bits format, it
can cause
trouble).
The problem is IMHO located in src/client.c
Here comes RFC portion & sample SMTP sessions
> 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:
>
> - Before sending a line of mail text, the SMTP client
checks the
> first character of the line. If it is a period, one
additional
> period is inserted at the beginning of the line.
>
> - When a line of mail text is received by the SMTP server,
it checks
> the line. If the line is composed of a single period, it
is
> treated as the end of mail indicator. If the first
character is a
> period and there are other characters on the line, the
first
> character is deleted.
