Only some mailboxes don't accept incoming messages, no error in the logs for this?!

[Daniel Eckl]

Last time I had such a problem, the recipient accidentially discarded 
all mails using a sieve rule. Could this apply to you, too? Can your 
customers set sieve rules?

Perhaps they aren't discarded, but forwarded without storing locally?

Best,
Daniel
