SMTP Recipient limitations?

Scott Walker_2 — Wed, 09 Mar 2005 18:08:45 GMT

How many recipients will the SMTP service process in one single e-mail message? I have notice that not all of my list from a mass mailing gets processed.

Open VMS 7.3 Vax

Thanks for any help,

Scott.

I don't know what the limit is but there is one which I why people majordomo, mx or other software to do mailing lists.

Hi,
as far as i recall there is no limit on number of recipients but a 255 char limit on the recipients field.

I have to assume the 255 limit is field entry limit for the screen buffer in VMS mail. This would only amount to 20 or so e-mail addresses and I know I'm getting more sent than this. I am sending the list from a P.C. Client directly to the SMTP Process on the VAX on port 25.

Are you using a VMS MAIL distribution list?

I think smtp has line length limitations.

I am not using a VMS Distribution list. This might be an option though. On the other hand I don't know if I can initiate it's use through a client like outlook.

If I can't find someone who knows this I may use myself as a recipient with a couple of thousand messages and count how many arrive.

I ran my test and logged the transactions from the P.C. side. I get exactly 500 recipients and then this message...

RX: 250 < >... Recipient OK
Error: Recipient count exceeds licencing imposed limit (State 23).
TX: QUIT
RX: 221 venus.testvax.com Service closing transmission channel

Any ideas how to increase this licence limit?

What TCPIP product are you using?

Scott,
I would try using a VMS distribution list.
mail @list_name.dis. You could create the list_name.dis file directly on VMS (or on your PC) as a text file with one address per line. I tried sending a bunch of messages to myself and only got one. So I sent messages to myself at different email addresses and got 18 messages.
You could try sending a test message from a VMS distribution list asking the receipiants to respond. You would get a lot of emails but you could look at the name farthest down the list. If you get a response from the last person on the list, then you're done.

The out of the box installation that comes with VMS 7.3 - not the ucx option.

I see that I cannot rate your answers anymore. I thought I could do this on the fly, but I see that they are all coming up unassigned. Sorry - new to using this lists.

ex DEC employee that missed VMS enough to buy a VAX from ebay, and loving it!
