I am writing you concerning the following issue with "postfix", any e-mail message over 3 MB doesn't go through and I receive the here below message:
"An error occurred while sending mail. The mail server responded: 5.7.1 Your email is rejected - probably spam!. Please check the message and try again"
Everything goes well with messages under 3 MB.
Please advice on what settings should I change in order to allow traffic over 3 MB - to increase this limit up to another level.
Thank you in advance,
