Great points!  I was having a similar issue and found as long as messages were under 5mb the problem went away.  Unfortunately with the larger messages it will take the extra step, so I've just been telling people who send me large attachments to upload it to dropbox or google drive (both are free) and send me the link.  Good luck!

I am using Pegasus 4.63, Windows 7, and my online email account is through BTYahoo.

When I try to download my email, if one of them has a large attachment (e.g. 7MB), the progress indicator goes gradually to 99%, then it just stops.  If I exit and then reenter Pagasus, then the large email appears, but it never gets to more recent emails, so they stay on the server.  When I look in BTYahoo, the large message and all more recent messages are still there, with the large message flagged as having been read and the more recent ones not read. Subsequent iterations of the above will result in multiple copies of the large email in my Pegasus inbox, but never any more recent emails.

I found one posting (Re: How to deal with Messages Pmail can not take off the server) that suggested increasing timeout to 300 (tried that) or turning off MTU discovery (I do not know how to do that).

Help!

that is a big email, you might have to live with deleting those emails manually by logging into BTYahoo. The MTU is more commonly set on wireless routers, we used to change it from the 1500 default and back it off to 1496 and sometimes that helped. If you have a slow internet connection, you can even knock it down further. Since your bandwidth is inversely proportional to the square root of the probability of packet loss, the greater your connection speed, the greater is your tolerance to packet loss. A small amount of packet loss can yield the entire email un-reconcilable, i.e. the application is stuck waiting for packets it thinks it still needs. So, how fast is your internet connection, and can you live with occasionally deleting an email server side until you upgrade connection speed? I generally tell people to keep email under 5 Mb and you seem to be stuck slightly above that rule of thumb.
