The MUA needs to send an EHLO to an MTA, it's how it finds out what the 
server supports.. I think this is a problem with configuration, but the 
this isn't really dovecot related, so probably doesn't belong on this list.

I might suggest that different email clients might respond differently 
to an advertisement of PIPELINE, so he probably should turn pipelining 
off in the MTA.. And start from there..
