I've noticed lately that Dovecot seems to be inserting an extra dot in some url's contained in html email. The most consistent example I see is in the newsletters from the Washington Post.
For example, if I look at the raw email on the mail server I see text that starts
<http://link.washingtonpost.com/click
But if I look at what Thunderbird shows it starts
http://link..washingtonpost.com/click/
I don't think its Thunderbird adding the dot, since K9 mail on my Android phone shows the same issue. It's only after the IMAP delivery that the extra dot appears.
We are running dovecot 2.0.12
Incidentally, the newsletter is full of these link.washington post url's. For each article it appears 3 times, once on title, once on a "read full article" link, and one on a picture. Its only the one on title, that gets the extra dot after its been through dovecot. Furthermore, it only happens from the second article on.
Any ideas?
