Hello Roelof, Thank you for your reply.
In answer to the first point in your reply, I am indeed using the mass mailing feature of The Bat. Regarding the possible causes of the error, it's true that I have duplicate entries in my Addressbook, if one counts as duplicates those entries that have the same email address, but are otherwise different (including having a different nickname (handle)). As for the copy of the email to be sent to me, I'll consider creating a webmail address and include it in the group of recipients. The reason that I wish to have this copy of the email message, is to indirectly check that my emails have been duly sent by my mail provider (ISP). The alternative of asking for a delivery report would create too much traffic for me. -- Best regards, Costas ________________________________________________ Current version is 3.95.03 | 'Using TBUDL' information: http://www.silverstones.com/thebat/TBUDLInfo.html
