However there are conflicting statements in RFC regarding single dot. Here are the RFC statements:

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.

>> This says remove dot even in case of single dot followed by charactes other than CRLF. IT SHOULD HAVE BEEN IF MORE THAN ONE DOTS.

In my opinion single dot case is not a valid test case.

There are two statements there, one applies to the sender, and one applies to the receiver.

In your example, you have a bug in the sender (not your software) AND a bug in the receiver (your software).

You CAN fix the bug in your software - ie do what (2) above says - if the first character is a period, and it's not on a line of its own, delete the first character. Statement (2) above isn't ambiguous.

You can't fix the bug in the sending software (unless your software does that as well...) so don't worry about that. If the developers of the sending software complain that your software shouldn't remove the leading '.' unless there's two of them, you have plenty of ammunition to defeat their arguments!

I can't see it being hard to fix the bug in the receiving software...
