Maximum Group Size for sending

Using Outlook Express there seems to be a limit to the size of group for sending emails. Around about 40 I believe
Is this a Plusnet limit or something Microsoft have done

Re: Maximum Group Size for sending

As I understand it we don't set any limit on the number of recipients (though there are measures in place to stop spamming) so I'd guess at a limit set in the program.

Matt,
I can't find any restriction in Outlook Express - could it be an Ironport problem now that outgoing emails apparently go through it

Re: Maximum Group Size for sending

Just checking with networks, our inmx - incoming mail - servers (I apologise for the misinformation in the above comment) have a limit of around 30 though it should be higher on the ironport boxes.
So yes, it seems to be set on our side, mainly to avoid spam.

Re: Maximum Group Size for sending

Thanks Matt,
Perhaps that should be added to a FAQ somewhere as 30 isn't a very large number for a group mailing list
I assume that incoming mail is mail coming into your servers from customers using relay.plus.net

Re: Maximum Group Size for sending

I'm interested in what errors you get Jim because this isn't something I was familiar with?

Re: Maximum Group Size for sending

It wasn't me it was SWMBO and she got round it by splitting the group.
The error was a bit odd.
It was something on the lines of one of the addresses being incorrect. The odd thing is that normally when you get that error it sends it to the rest of the recipients but in this case it wouldn't send any at all.

Re: Maximum Group Size for sending

Sounds like a rejection at the SMTP level in which case I'd have thought it's be the relays causing the problem as the mail hits them before the IronPorts. I could be wrong though.
