[fetchmail-users] antispam 501 doesn´t delete mail from pop3

[Aljoscha V. <vol...@vo...>]

Hello dear fetchmail users,

this is my first post to a mailing list ever, so please don´t get too 
mad at me if i make a mistake.

I´m currently using fetchmail-6.3.11-r1 on a gentoo-based mail server.

Fetchmail gets mails from a remote pop3 server and feeds them to a local 
postfix installation.

Today i got a malformed mail, 501 - Illegal address syntax, according to 
postfix. It´s got a "-" as the first character, clearly invalid.

I added "antispam 501" to the "defaults" section of my fetchmailrc file, 
but that didn´t help, so i added fetchall as well - again, to no avail. 
Fetchmail still says "not flushed" on every run and i get an ugly error 
in my postfix log.

I´d like fetchmail to just delete the mail, what should i do? I´ve read 
tons of threads with this kind of problem, however they almost all get 
resolved by adding the antispam option.
Am I missing something?

Kind regards,

Aljoscha Vollmerhaus
