My usual limit is 100MB and then I explain to my users that: 1) That's the _email size limit_ and not the size limit for an attachment to an email 2) Email is inefficient when used for transferring files, thus overhead 3) Email is not intended to be a system for routinely moving large files 4) You can't garuntee what other mail servers in the chain may have enabled as maximum size limits, so upping the local limit isn't going to solve all your problems 5) Look at OneDrive, Dropbox or Google Drive as readily available ad-hoc file transfer options.
At 100MB I hear very few complaints. I certainly wouldn't be making the limit any higher for the OP's scenario. Some legacy mail systems I have to deal with, struggle with the combination of large email + large number of recipients (when processing rules require you to bifurcate the email into one-email-per-recipient in order to enable per-recipient rule handling, your single 100MB email can become several gigabytes of processing) so that's another potential factor.

Do you take into account the 4/3 inflation with Base64 encoding and / or allow for any message body when setting the maximum message size that your servers allow? -- Grant. . . . unix || die _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
