Thanks. I reordered the smtp list for all identities so that the appropriate server was at the top of the list. That worked. When I go back to AZ I will reverse them. Thanks for the help.

I've been using PM for a couple years now and have this same problem every spring & fall when we change winter locations. I receive mail in NY via *.rr.com and in Az via *.cox.net. I set up my outgoing smtp server accordingly for each location and have no problems when I send/receive new mail at each location. The problems occurs when I receive an email while in AZ, then try to reply to it from NY (after I reset the outgoing smtp server). Pegasus tries to connect to the AZ smtp server instead of the NY smtp server. I have multiple identities set up but they all share the same network config profiles. Is there a setting or something I'm missing to direct the old mail from AZ to the NY server? Any help would be appreciated.  

POP3 and SMTP host configuration files are shared but each identity gets configured for which ones it is to use.  So when in NY you need to disable the AZ SMTP host and enable the NY SMTP host in every identity and when in AZ you need to disable the NY SMTP and enable the AZ host in every identity.  Either that or create NY and AZ identities and configure each appropriately.
