Hello everyone

I am having a little problem here. Mails coming from spamgourmet.com do not make it to my inbox. However, when I send directly from Gmail, it works fine. I noticed in /var/log/maillog that the max message size in postfix was set higher than the default max mailbox size. So I set the mailbox size to 10Gigs.

Still no cigar.

I also notice that I receive no more mails from my various systems that used to send to the postmaster mailbox.

I see "removed" messages in /var/log/maillog:

How do I find out for what reason this doesn't seem to be delivered?

Thanks a lot in advance!
