Hello. Sorry for the long quote, I think it's neecessary.

Please, read the question again, and again, and note this part: "I need to send and receive mail using addresses like antonio@bemarnet.es ^^^^^^ instead of antonio@host.bemarnet.es". > Many people does not use m4 at all to configure sendmail. Of course, it is Wrong! Sendmail is configured that way. I do know tat you tweak an existant sendmail.cf file, but the *correct* way to do it is to use the cf/ tree. > generally perfectly adequate to use the MASQUERADE_AS macro, but it likely > does no more than putting a DM symbol definition in the .cf file. This is Wrong!!!!! Many rewriting rules change if you masquerade!!!! Configure a sendmail in the right way, i.e. use m4 and then use diff to see it yourself. > essentially the same as above, but hides it somewhat. I do not see a clear > advantage, and it is not advisable to use the m4 approach if their .cf > file is locally customized without m4. One first needs at least to see the > file to decide. Wrong! Any customization can be done in the .mc file, and this is the right way to do it. > Your method is only one approach, not the only one as you imply. Wrong! Using m4 is the only *correct* approach.
