Using Mercury Transport with Postcast Mail Server

Got it working [:D]

 

Then promptly broke it  [:'(]

Hello,

 Is it safe to use Mercury with Postcast Mail server?

 Postcast is only for OUTGOING email and I use it to relay email from within my network outbound.

Mercury will be used to gather all external email that is INBOUND to me

and then it will be picked up by me from there.

Thanks

Note: I just did some more reading and it appears I could ditch Postcast server and use Mercury for both incoming AND outgoing?

Yes, no and maybe.  As you have noted, Mercury/32 has the ability to send mail directly using MercuryE but if you do not have a fixed IP address with a registered host name and PTR record many receiving servers will reject your mail as spam.  Also many ISPs block outbound port 25 connections.  If Postcast is sending directly from your system using port 25 and you do not have the fixed IP address it will be blocked/rejected as well.  That said, I've only reviewed what the Postcast web site says about the SMTP server so it may be sending via a relay host someplace else.

Hi Mr. Stephenson and thank you for the reply [:)]

 I suppose I could contine to use Postcast for outgoing mails and use Mercury only to gather

INBOUND emails?

Or, would the programs conflict with one another?

Thx

[quote user="mistypotato"]Hi Mr. Stephenson and thank you for the reply [:)]

 I suppose I could continue to use Postcast for outgoing mails and use Mercury only to gather INBOUND emails?

Or, would the programs conflict with one another?

No conflict, you would not be using the Mercury/32 queue or SMTP host to send the mail to Mercury/32 nor MercuryE or MercuryC to send the mail from Mercury/32 so they would not be loaded at all.  

FWIW, I looked at Postcast further and it appears thay have all of the problems with port 25 blocking and blacklists that cause MercuryE a problem.  They do have a handy tool though to fallback to using a relay host for those hosts that bounce the mail and this does seem to be a way around the blacklists.

Thx

Hi again,

 

wow.. didn't take me long to cause a problem.

I mistakenly thought I could best learn this by jumping in but now I backing off and trying to read the docs in depth.

 I went to configure the pop3 server and all of a sudden it started downloading all emails from a remote server and then deleted them all (not good).  So, I'm now trying to figure out where all those emails went and why it automatically deleted them all off the remote server....I was expecting to see an option somewhere to either leave or delete the message off the source server but don't see that option?

 Where would pop3 emails land after being retrieved off a remote pop3 server?

thx

MercuryD probably found no matching domain and/or alias and there was no default user so the mail was deleted.  From the help:

Default user  When distributing mail from a domain mailbox, MercuryD may encounter messages for whom it can find no local recipient; this will commonly happen if one of your users subscribes to a mailing list, since mailing lists usually do not indicate the actual recipient anywhere in the message headers. In cases such as this, MercuryD can be told to deliver the message to a specific, or default user. If you leave this field blank, MercuryD will discard any messages for which it can find no local delivery addresses. This field is only meaningful when you have told MercuryD to distribute mail (by leaving the Local user field blank).

If there was no domain and user matching the mail downloaded  and no default user the mail is quietly deleted.

So, I'm now trying to figure out where all those emails went and why it automatically deleted them all off the remote server....I was expecting to see an option somewhere to either leave or delete the message off the source server but don't see that option?

There is no option to leave the mail on the server.  Mercury/32 is a mail server not a POP3 mail client so it always downloads all mail on the server.
