My daughter needs to send me a large file. It appears that it is getting
through my ISP, but being rejected on my CentOS mail server. The message
she's getting says

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

anne@localhost
SMTP error: 552 5.3.4 Message size exceeds fixed limit
Reporting-MTA: dns; borg2.lydgate.lan

I presume that this is a configurable limit, but I'm not sure where to look.
Since it says MTA I'm thinking that it's probably postfix. Can someone
please tell me what parameter I'm looking for? Thanks

I have reams of documentation printed out. I'll start wading through that
tomorrow, but time is of the essence with this one.

I believe the following is about 30MB in postfix.
mailbox_size_limit = 30000000
message_size_limit = 30000000

If it's postfix, the parameter is message_size_limit -- the default is
10240000 (10MB) if it's not explicitly configured. This parameter
goes in main.cf.

postfix (main.cf):
message_size_limit=<numberOfBytes>



sendmail (sendmail.mc):
define(`confMAX_MESSAGE_SIZE', `<numberOfBytes>')


sendmail will need a 'make' to be run in the conf dir (probably /etc/mail)

Is that 2.5 TB? I must be getting old. When I was young, I thought
10MB was big.

So 'size_limit' is what I'm looking for. Thanks everyone. Now comes the
really hard bit. I have to tell her, blindfolded, how to tell the size of
the message she is sending. She uses btinternet's yahoo mailer, and I
haven't a clue what she can see there. :-(

I think I do have 2 too many.

Much as I dislike getting or giving "you asked for x, but here's how
to do it with y" I'm going to do so here.

Email is one of those things which is great for small files, and such,
but large transfers can cause issues at pretty much every aspect of
the trip. If you've already got a webserver running, add a password
protected area for uploads. You can even set it up to allow webdav
style transfers over https. This avoids any mail handling delays, lets
both parties know it got there successfully, and keeps the clutter out
of the mailserver.

get 'properties' (usually a right click on the file) of the file she's
attaching
