Question / Problem

I have no problems sending mail to small groups, but I get error messages, if I try to send mail to larger groups (e.g. 250 recipients). "SMTP Server error: Socket Error #100xx / #110xx. Connection reset by peer. ---" I know from former mailings, that the mail addresses are all valid.What does it mean?

Answer / Solution

Although this errormessage could appear under many conditions, most of the time -in the described scenario- it simply means, that your provider limits the amount of emails you can send via this server in a certain period of time. E.g. you may send only 20mails every 20 minutes. Please ask your provider about the details of these limitations.
