Frozen Message Error / Smtp, Error code -173 / SMTP error 554

[Dark Shadow]

I set up PHPXmail about a year ago I have 7 virtual domains and I could never get a message to send via smtp.mydomain.com to I set my email program to my ISP's smtp and the mail to my domain and that works fine. I would love to work out what is wrong why I cant use smtp.mydomai1.com, smtp.mydomain2.com etc to send emails.
I recently set up a PHP form program and this seems to send my emails fine.
I have dozens of frozen messages with errors like the following:
Logfile for frozen message 1217047625040.14991370.d1.Server_3, 0, 5

<<
ErrCode = -173
ErrString = Mail loop detected
Message blocked by mail loop check !
SMTP-Error = "554 Message blocked by mail loop check"
>>

can any one give me any ideas where to start looking to solve this loop problem.

Any help greatly appreciated

Could you help with this one-

I assume you want to forward outgoing mails thru your provider's SMTP. If so, disable DefaultSMTPGateway and use smtpfwd.tab instead. Please post new questions under new topics.

Thank You Harold,

I have converted a NAS server to a web server and modded it to host 7 domains (has taken alot of detemination and perseverance a very steep learning curve) what I really want to do is have a SMTP for each domain

ie smtp.domain1.com, smtp.domain2.com etc. This lets me send out mail from any PC/ISP, currently in my mail client I have set up the outgoing server as the ISP's smtp server and this works fine, however if I plug my laptop into another network it will not send emails as my ISP blocks requests to access their smtp server by computers connected through another ISP.

Many thanks

So you are looking for a SMTP proxy which routes mail from your laptop to your home's ISP ?
