Does anyone on here know, for a fact, if BT limit the number of recipients that you can send email to, when using their outgoing mail servers?

I've just had a rather lengthy conversation with a customer, who has a legitimate bulk mail to send out, using a piece of software called 'Anconia'.

Apparently, if they set Anconia to send to any more than 10 addresses at a time, the mail server dumps the connection, and the sending fails. They called BT Support (there's an oxymoron, if ever I heard one) and were told there was no limit :confused:

Any ideas?

I'm about to try reconfiguring them to use the mail servers I use, to see if the Anconia software is at fault, or if it is BT, but I wondered if anyone had any experience of this issue ... ?

do you mean when using the cc function??

i think there is a limit to the amount of data which can be contained in the header of the email, this is common to all email and not just BT....

i've got some info on it somewhere from my A level computing days, i'll see if i can find it later on

do you mean when using the cc function??

Not exactly ...

I'm not sure how Anconia formats the emails it sends (I haven't used it myself), but I assume it uses the CC: or BCC: fields.

I used to administer the mail servers when I worked for TEAMtalk, and I recall we used to recommend that customers kept the address fields down to 100 max (less, preferrably!), but dropping the email with more than 10 recipients seems a little odd ...

I'm about to try the '1 And 1' servers, see how they cope :P

i think it may be an anti-spam feature, i've been having lots of trouble with bt email recently.... somtimes i cannot send emails at all even with only one recipient

Good Ol' BT

They will most likely be using the BCC field. Maybe they have limited the number of recipients in this field because its usual use is to hide email addresses that spammers are sending to.

If you are a corporate customer with a non domestic IP address, run your own SMTP server bypassing the ISP entirely like I do from home.

Run their own mail server? :eek:

That'd be worth seeing! They have enough trouble running Outlook

Actually, thats maybe a little harsh ...

Sadly, they're not on fixed IP, nor do they have an IT guru at their daily disposal, so things have to be kept simple(ish). I have suggested a couple of upgrades to them to bring their IT 'up to speed', but so far ...

I've just spoken to them again ...

BT originally told them that there was, categorically, no limit to the emails they could send.

BT have, about ten minutes ago, completely contradicted that last conversation. :confused:

BT now say that they'll call my customer back (not 'til Monday at the earliest, apparently) to confirm that "they're no spammers", and then lift their mail limits.

So it must be done on a case by case basis ... would be nice if they mentioned this in their "Support" pages. The subject isn't even covered, not that I could find.

I can feel the need for caffeine and nicotine coming on, rather strongly ..... :P

Have they remembered to set up SMTP authentication in this extra software? I think BT require you to log in to their servers before you can send mail, now.

They have indeed. Or at least I assume they have :P .. without it they wouldn't be able to send any mails at all.

Note to Stuart: if you ever happen to enter the hallowed rooms of Briskoda, and stumble upon my "They have enough trouble running Outlook" comment, it was them clowns wot made me say it, honest

They do. My father was trying to send some email from some one else's broadband (BT) and even though he changed SMTP servers, he had to authenticate with that broadband
