In trying to figure out what differs between the two cases, I see that if
the message includes an attachment with a filename like this:
filename*=ISO-8859-7''%C4%EF%EA%E9%EC%E1%F3%F4%E9%EA%FC.doc
the link that IMP 4.1.3 offers for downloading is like this:
https://webmail.auth.gr/horde_for_stpetrak/services/download/?module=imp&thismailbox=INBOX&index=1060&
mailbox=INBOX&actionID=download_attach&id=2&mimecache=8bec980a27dabc720f1e028b02d27a30
&fn=%2F%25CE%2594%25CE%25BF%25CE%25BA%25CE%25B9%25CE%25BC%25CE%25B1%25CF%2583%25CF%2584%25CE%25B9%25CE%25BA%25CF%258C.doc
Notice that the originally 11 char long filename was incorrectly
translated into a 22 char long filename, probably due to an inappropriate
UTF-8 conversion.

On the other hand, if the message includes an attachment with a filename
like this:
filename*=%C4%EF%EA%E9%EC%E1%F3%F4%E9%EA%FC.doc
the link that IMP 4.1.3 offers for downloading is like this:
https://webmail.auth.gr/horde_for_stpetrak/services/download/?module=imp&thismailbox=INBOX&index=1061&
mailbox=INBOX&actionID=download_attach&id=2&mimecache=a112acf7855208dfd1c1cc07265d542c
&fn=%2F%25C4%25EF%25EA%25E9%25EC%25E1%25F3%25F4%25E9%25EA%25FC.doc
Notice that the originally 11 char long filename was correctly translated
into a 11 char long UTF-8 filename and it is correclty downloaded by
IExplorer.

Hope all these can be of help.
