Hi,
we encountered a strange behavior on some of the invitation mails we send out. In such mails a dot (.) was removed from the survey url. Therefore the recipient got a 404 when he clicked on the link.
May I ask if someone else has seen this before?
We think this might have to do with the SMTP dot suffering.
Here is a extract of the
SMTP RFC section 4.5 of rfc2821
for details:
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.
Any idea how to avoid this is welcome.
Thanks a lot!
Oliver
