Many thanks to those who replied to my question, they helped to point me in the right direction to determine that the cause of the problem was in fact my fetchmail configuration and not exim. I appreciate that my use of fetchmail and exim to route my incoming mail locally may not be ideal and is something of a sledgehammer to crack a nut but it fits my needs very well and has normally performed without problems. In order to reduce spam when purchasing online I like to use unique email names so if I'm buying from somesupplier.example I'll give my email name as mike-somesupplier@ so I know who to blame and blacklist if I get spam to that name. To avoid having to keep reconfiguring my mail system every time I use a new address I wanted something which would route all these throwaway names to the appropriate user's mailbox and found that exim was very good for this with it's ability to handle wildcards in alias names. Although envelope details are lost when an email arrives in a POP3 mailbox, fetchmail is able to recreate them. For the other servers I collect from the recipient is picked up from the Envelope-to header but the server for the mailing list was running qmail which does things differently. Since fetchmail failed to find an Envelope-to header it tried to determine the recipient by looking in the To and Cc headers for email names matching the domain which I was collecting for, it then passed RCPT data for both names to exim which then, quite correctly, attempted to delivered one locally and the other via the external smarthost. I've now changed the fetchmail config file to tell it to use the Delivered-To header from this server and everything works fine. -- Mike Clarke -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
