dumbest questions about limit
Hi Sorry about probably dumbest questions. What does it really mean? 552 5.3.4 Message size exceeds fixed limit Apr 16 16:03:48 thebe4 postfix/smtpd[11692]: NOQUEUE: reject: MAIL from mail-il1-f169.google.com[209.85.166.169]: 552 5.3.4 Message size exceeds fixed limit; proto=ESMTP helo= Apr 16 16:03:48 thebe4 postfix/smtpd[11692]: too many errors after MAIL from mail-il1-f169.google.com[209.85.166.169] Apr 16 16:03:48 thebe4 postfix/smtpd[11692]: disconnect from mail-il1-f169.google.com[209.85.166.169] ehlo=2 starttls=1 mail=0/1 commands=3/4 in postfix i set message_size_limit = 2324 mailbox_size_limit = 0 postconf -n |grep "_size_limit" mailbox_size_limit = 0 message_size_limit = 2324

An incoming mail will be refused if its size exceeds message_size_limit (in bytes). It is undocumented (and not recommended) to use message_size_limit=0 meaning 'no limit' - although mailbox_size_limit=0 is valid/documented. Although your postconf is reporting 2324 (a little over 22MB), you can (and may) have different settings in master.cf which override this - for instance for authenticated vs non-authenticated incoming mails.

Otherwise it would be a way for clients to get round the size restriction, and send unlimited data.

I just wanted to add that the client does not check for provided SIZE option and thus it's possible that oversized message was transferred. -- Matus UHLAR - fantomas, uh...@fantomas.sk ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
