E-mail több címre egyszerre

Te a Bcc-t keresed (Blind carbon copy). A To mezobe pedig sajat e-mailcimet irsz. Igy a cimzett azt hiszem nem fogja latni a sajat cimet sem (ill. nevet), de ez altalaban elhanyagolhato problema.

Ha tul sok a cim, akkor egyszerubb ha felraksz valami listakezelot a serverre es behuzod az osszes cimet abba. Ugy rendesen fog latszodni a cimzett neve is, illetve nem kell foglalkoznod az SMTP server altal egyszerre maximum fogadott cimekkel (nem tudom mi a korlat beallitas neve).

MAIL(1)                   BSD General Commands Manual                  MAIL(1)

NAME
     mail, mailx, Mail -- send and receive mail

SYNOPSIS
     mail [-eIinv] [-a header] [-b bcc-addr] [-c cc-addr] [-s subject] to-addr [...] [-- sendmail-options [...]]
     mail [-eIiNnv] -f [name]
     mail [-eIiNnv] [-u user]

DESCRIPTION
     mail is an intelligent mail processing system which has a command syntax reminiscent of ed(1) with lines replaced by mes-
     sages.

     The options are as follows:

     -a      Specify additional header fields on the command line such as "X-Loop: foo@bar" etc.  You have to use quotes if
             the string contains spaces.  This argument may be specified more than once, the headers will then be concate-
             nated.

     -b bcc-addr
             Send blind carbon copies to bcc-addr.

NAIL(1) User Commands NAIL(1)

NAME
nail - send and receive Internet mail

SYNOPSIS
nail [-BDdFintv~] [-s subject] [-a attachment ] [-c cc-addr] [-b bcc-
addr] [-r from-addr] [-h hops] [-A account] to-addr . . .
nail [-BDdeHiInNRv~] [-T name] [-A account] -f [name]
nail [-BDdeinNRv~] [-A account] [-u user]

DESCRIPTION
Nail is an intelligent mail processing system, which has a command syn-
tax reminiscent of ed(1) with lines replaced by messages. It is based
on Berkeley Mail 8.1, is intended to provide the functionality of the
POSIX mailx command, and offers extensions for MIME, IMAP, POP3, SMTP,
and S/MIME. Nail provides enhanced features for interactive use, such
as caching and disconnected operation for IMAP, message threading,
scoring, and filtering. It is also usable as a mail batch language,
both for sending and receiving mail.

The following options are accepted:

-A name
Executes an account command (see below) for name after the
startup files have been read.

-a file
Attach the given file to the message.

-B Make standard input and standard output line-buffered.

-b address
Send blind carbon copies to list. List should be a comma-sepa-
rated list of names.

-c address
...

A nail márcsak azért is jobb, mert van egy "-a file" funkciója.

Én a mutt-ot javaslom, kb. így:

ciklus vegig a cimzetteken
mutt -F sajat_muttrc -a attacsment cimzett < levelszoveg.txt
ciklus vege

A -F sajat_muttrc nem feltetlen kell, de ebben lehet definialni sajat header-eket, stb. Ha igy csinalod, akkor mindenki egyetlen cimzettet lat, sajat magat.
