[Fetchmail-users] wrong message length on every message

[hput <hp...@zo...>]

0S: ubuntu-21.10
fetchmail release 6.4.22+SSL-SSLv2-SSLv3+NLS
-------       -------       ---=---       -------       -------

At one of the  pop3 servers I use I get messages like the one below for every
message (wrapped for mail):

,----
| fetchmail: message bl...@zo...@pop.zoho.com:12 was not the
| expected length (1513 actual != 856 expected)
`----

At another  pop3 server I use, nothing like that ever happens.

So suspicious it may be on the server side.  As you see that is:
zohomail.com

Can any of you here tell me what to make of the messages and whether
it is likely a server problem or not.
