It's the same issue. Whether sending or receiving attachments: http://forum.parallels.com/showthread.php?t=85508

I switched to QMail and all my problems went away. Although with QMail you do get bare LF issues, but that can be fixed easily.

Thanks.
 
Very weird

I never had this problem when receiving emails, was only when sending, anyway i increased the smtpt connect time from 30 to 90..so far so good..

i'm really considering switching to qmail, but i faced that LF problem as well...which i didn't find any solution to...

So i'm stuck nowhere@!

Increasing the timeout will cause you more problems.

I was worried about switching to QMail too but it was so easy. Just one line:

/usr/local/psa/admin/sbin/autoinstaller --select-release-current --install-component qmail

The bare LF issue is completely fixed here: http://forum.parallels.com/showthread.php?t=94222

I had errors when compiling but I fixed that (as you can see at the end of that post).
