Hi Rick

I was looking thru the doc, but I could not find if there is a limit to the # of recipients that can be specified or the length of the string holding the address when sending. When Sending, I have nMailMode = 2 so sending is via sendmailclassic. My code has caught Error 2027 when sending. My list of recipients has recently grown and I am thinking I might be exceeding a limit?

Thanks! Matt Cummings

@Matt,

That almost certainly will be determined by the mail server that's receiving your message.

But... word of warning. Most mail servers and email clients will bounce messages that have too many recipients or at minimum quarantine them.

If you're doing bulk mailing and you want all recipients to actually receive messages, I highly recommend you send messages one at a time repeatedly.

Thanks Rick,

I adjusted the code to do individual sends for each recipient and all good now.

Thanks for the quick response.
